Gift Import Batches consist of a batch header record followed by a collection of gift records.  All records are CSV types commonly delimited by semi-colons although commas are acceptable. 
== Description of Current Implementation in Open Petra (October 2014) ==


=== Batch Header Record fields ===
The purpose of this entry is to define the Gift Batch file layout and the way in which the data is validated.
 
Gift batch import records must be in CSV format, i.e. variable length fields separated by a delimiter (commonly a semi-colon, although commas are acceptable) with text fields enclosed in quotes.  A position in the record must be left for each field, even if the field is empty.
 
The CSV format file is, of course, human readable but may contain accented characters (for a donor's name for example) and the file may be encoded in a number of different formats.  There is a special wiki page devoted to [[Text File Encoding in Open Petra]].
 
The file is parsed line by line and, provided there are no errors, the batches are saved to the database.  However, if there are critical errors no data is saved.  The whole file content is rejected.  But an attempt is made to read the file in its entirety so that a complete list of errors is built up and can be reported to the user. If more than 100 messages are found then the read is aborted because this is usually symptomatic of the same error(s) being duplicated many times over so there is little point in continuing.  The goal is that the user should present the file to Open Petra and get a list of a few mistakes, which can all be corrected so that at the second attempt the file is parsed correctly.
 
Note that multiple mistakes on a single line are all reported.
 
Validation is performed at five levels:
* ''Parsing''.  Each token is parsed as one of string, boolean, Int64, Int32 or Date. If the text in the file does not convert to the expected data type a parsing error is generated and a 'default' value is assumed so that it is possible to continue reading the file.  For numbers a default value of -1 will be assumed, which is typically an invalid value, but this is preferable to using a default that might be valid.  For decimals a value of 1.00 is assumed and for a date: 'Today'.
* ''Standard Open Petra Validation''.  This is the validation that checks that critical strings are not empty, that strings do not exceed the allowable character count and so on.
* ''Additional Open Petra manual validation''.  The finance modules have additional validation that follows the standard Open Petra Validation Framework and is used to check the 'business logic'.
* ''Import-specific validation''. While most validation falls into one of the above categories there are a few cases where the validation is import-specific.  So, for example, the number of columns in the row must be correct and the first row of a file must describe a Batch and not a Gift.
* ''Foreign Key Exception Handling''. The intention is that the validation performed using the Validation Framework should mean that this level of exception handling never occurs.  However there is specific foreign key exception handling in place that will show a 'friendly' message should an attempt be made to submit a row to the database that has a foreign key error.  If this does occur, reading the file will stop at the offending row.
* ''Other Exception Handling''. The intention is that as far as possible validation should read the whole file detecting errors and reporting them once the file has been completely read.  Until the first error has been found each row is provisionally added to the database, but once the first error has been found this process ceases, because attempting to add a bad record to the database would cause an 'exception' to be raised which would bring the import to a halt on that line.  However, if some aspect of validation has been missed in the design of the code, any database errors will be handled by a 'master exception handler' and the reason displayed and code will stop reading the file on that row.
 
Gift import batches consist of a repeating sequence of a batch header record followed by a collection of one or more individual gift records.
 
=== File Structure ===
Any lines that start with # or /* are treated as comments and are ignored.
The first line in the file should be a 'Batch'.  If the first line is a transaction, the code will create a dummy batch so that the file can continue to be read (but nothing will be saved to the database).
A Batch Header Record must contain 9 columns. A Gift Record must contain either 21 or 27 columns (there are two possible formats).
 
=== Batch Header Record ===
'''Row Type''' - “B”
'''Row Type''' - “B”
: '''Validation Rules''': There must be 9 columns
'''Batch Description''' – <nowiki>[80ch. maximum] </nowiki> Required.  Gift batch description
: '''Validation Rules''': Cannot be empty field. Length must be 1-80 characters.
'''Bank Account Code''' – <nowiki>[16ch. maximum] </nowiki> Required.  The bank account code for the batch. For a normal gift this should be an active bank account code. For "Gift in Kind" or "Other", it can be any active posting account.
: '''Validation Rules''': The code must exist in the a_account table and must reference an active account.  Import fails if the account is inactive.  ('''Incomplete Validation''')
'''Hash Total''' – <nowiki>[decimal] </nowiki> Required. As with entering a batch using the Client GUI, this value can either be zero or should be the anticipated sum total of the batch. A zero value would mean that the batch could be posted.  Any other value would mean that the batch cannot be posted unless the batch total and hash total are identical.
: '''Validation Rules''': The field cannot be blank.  There is no check at import time that a non-zero hash total matches the batch total. ('''Validation differs from spec.''')
'''GL Effective Date''' – <nowiki>[Date] </nowiki> Required. The date must be within the date range of the current and open forward periods.
: '''Validation Rules''': The date must be within the date range of the current and open forward periods.
'''Currency Code''' – <nowiki>[16ch. maximum] </nowiki> Required. Must be a valid currency code from the OpenPetra currency table. If the account specified above is a foreign currency account, then this entry must match the currency of the account.
: '''Validation Rules''': If the currency is not the same as the base ledger currency, there must be a pair of entries in the Corporate Exchange Rate table for the month in question.  ('''Incomplete Validation''')
'''Exchange Rate To Base''' – <nowiki>[decimal] </nowiki> Required. Cannot be 0. Enter the exchange rate at the time the deposit was made. If the gift currency is the same as the base ledger, then exchange rate must be 1.
: '''Validation Rules''': The exchange rate must be a positive decimal.  If the currency is the ledger base currency the rate must be 1.00.
'''Bank Cost Centre''' – <nowiki>[24ch. maximum] </nowiki> Required.  The cost centre which is applied to the bank. Must be an active local posting cost centre for the ledger.
: '''Validation Rules''': The cost centre code must exist in the a_cost_centre table and must reference an active account.  Import fails if the account is inactive.  ('''Incomplete Validation''')

=== Gift Record ===
'''Row Type''' - “T”
: '''Validation Rules''': There must be either 21 or 27 columns.
'''Donor Key''' – <nowiki>[Int64] </nowiki> Required.  The partner key of the donor. The donor must be entered as a partner before the gift batch is imported. Note that if the donor's partner record has been merged into another partner, then the new partner key must be specified instead of the key of the merged record.

'''GL Effective Date''' – Required. What are the requirements here? Does this date have to be within the date range of the current and following accounting periods? If empty, does it default to today's date? Are there any cross-edits with gift date?
The purpose of this entry is to define the Gift Batch file layout and its validation requirements.  The validation process should follow the OpenPetra validation framework.


'''Currency Code''' – <nowiki>[16ch] </nowiki>Must be a valid currency code from table a_currency: a_currency_code_c
Gift batch import records must be in CSV format.  I.e., variable length fields separated by a delimiter (commonly a semi-colon, although commas are acceptable) with text fields enclosed in quotes.  A position in the record must be left for each field, even if the field is empty.


'''Exchange Rate to Base''' – <nowiki>[Dec?] </nowiki>Cannot be 0. Any other constraints?
Gift import batches consist of a batch header record followed by a collection of gift records.

Description of Current Implementation in Open Petra (October 2014)

The purpose of this entry is to define the Gift Batch file layout and the way in which the data is validated.

Gift batch import records must be in CSV format, i.e. variable length fields separated by a delimiter (commonly a semi-colon, although commas are acceptable) with text fields enclosed in quotes. A position in the record must be left for each field, even if the field is empty.

The CSV format file is, of course, human readable but may contain accented characters (for a donor's name for example) and the file may be encoded in a number of different formats. There is a special wiki page devoted to Text File Encoding in Open Petra.

The file is parsed line by line and, provided there are no errors, the batches are saved to the database. However, if there are critical errors no data is saved. The whole file content is rejected. But an attempt is made to read the file in its entirety so that a complete list of errors is built up and can be reported to the user. If more than 100 messages are found then the read is aborted because this is usually symptomatic of the same error(s) being duplicated many times over so there is little point in continuing. The goal is that the user should present the file to Open Petra and get a list of a few mistakes, which can all be corrected so that at the second attempt the file is parsed correctly.

Note that multiple mistakes on a single line are all reported.

Validation is performed at five levels:

  • Parsing. Each token is parsed as one of string, boolean, Int64, Int32 or Date. If the text in the file does not convert to the expected data type a parsing error is generated and a 'default' value is assumed so that it is possible to continue reading the file. For numbers a default value of -1 will be assumed, which is typically an invalid value, but this is preferable to using a default that might be valid. For decimals a value of 1.00 is assumed and for a date: 'Today'.
  • Standard Open Petra Validation. This is the validation that checks that critical strings are not empty, that strings do not exceed the allowable character count and so on.
  • Additional Open Petra manual validation. The finance modules have additional validation that follows the standard Open Petra Validation Framework and is used to check the 'business logic'.
  • Import-specific validation. While most validation falls into one of the above categories there are a few cases where the validation is import-specific. So, for example, the number of columns in the row must be correct and the first row of a file must describe a Batch and not a Gift.
  • Foreign Key Exception Handling. The intention is that the validation performed using the Validation Framework should mean that this level of exception handling never occurs. However there is specific foreign key exception handling in place that will show a 'friendly' message should an attempt be made to submit a row to the database that has a foreign key error. If this does occur, reading the file will stop at the offending row.
  • Other Exception Handling. The intention is that as far as possible validation should read the whole file detecting errors and reporting them once the file has been completely read. Until the first error has been found each row is provisionally added to the database, but once the first error has been found this process ceases, because attempting to add a bad record to the database would cause an 'exception' to be raised which would bring the import to a halt on that line. However, if some aspect of validation has been missed in the design of the code, any database errors will be handled by a 'master exception handler' and the reason displayed and code will stop reading the file on that row.

Gift import batches consist of a repeating sequence of a batch header record followed by a collection of one or more individual gift records.

File Structure

Any lines that start with # or /* are treated as comments and are ignored. The first line in the file should be a 'Batch'. If the first line is a transaction, the code will create a dummy batch so that the file can continue to be read (but nothing will be saved to the database). A Batch Header Record must contain 9 columns. A Gift Record must contain either 21 or 27 columns (there are two possible formats).

Batch Header Record

Row Type - “B”

Validation Rules: There must be 9 columns

Batch Description – [80ch. maximum] Required. Gift batch description

Validation Rules: Cannot be empty field. Length must be 1-80 characters.

Validation Rules: The code must exist in the a_account table and must reference an active account. Import fails if the account is inactive. (Incomplete Validation)

Hash Total – [decimal] Required. As with entering a batch using the Client GUI, this value can either be zero or should be the anticipated sum total of the batch. A zero value would mean that the batch could be posted. Any other value would mean that the batch cannot be posted unless the batch total and hash total are identical.

Validation Rules: The field cannot be blank. There is no check at import time that a non-zero hash total matches the batch total. (Validation differs from spec.)

GL Effective Date – [Date] Required. The date must be within the date range of the current and open forward periods.

Validation Rules: The date must be within the date range of the current and open forward periods.

NOTE: This specification is a work in progress and has not yet been implemented. - Dwmosman 18:32, 27 February 2013 (UTC)

The purpose of this entry is to define the Gift Batch file layout and its validation requirements. The validation process should follow the OpenPetra validation framework.

Gift batch import records must be in CSV format. I.e., variable length fields separated by a delimiter (commonly a semi-colon, although commas are acceptable) with text fields enclosed in quotes. A position in the record must be left for each field, even if the field is empty.

Gift import batches consist of a batch header record followed by a collection of gift records.

Batch Header Record

Validation Rules: Cannot be empty. Must be an existing account in table a_account for the active ledger. Must be a posting account (a_posting_status_1). If gift type(a_gift_type_c) = MFinanceConstants.GIFT_TYPE_GIFT, then must be a bank account (a_account_property = "BANK ACCOUNT"). Generate a warning if the account is not an active account.

Hash Total – [decimal] Optional. If blank or 0, then this hash total will be ignored. If non-zero (plus or minus), then this will be compared against the sum of all gifts in the batch.

Validation Rules: If non-zero, then the hash total must equal the sum of the gift amounts from the batch.

GL Effective Date – [date] Required. The date must be within the date range of the current and open forward periods.

Validation Rules: Must be a valid date in the date format specified for the batch. Validate against period dates. Search for TFinancialYear.IsValidPostingPeriod. For an example, see csharp\ICT\Petra\Server\lib\MFinance\GL\GL.Importing.cs.

Currency Code – [16ch.] Must be a valid currency code from the OpenPetra currency table. If the account specified above is a foreign currency account, then this entry must match the currency of the account.

Validation Rules: The value must exist in table a_currency (a_currency_code_c). If the bank account specified above is a foreign currency account (a_foreign_currency_flag_1), then this field must match the currency of the account (a_foreign_currency_code_c).

Exchange Rate to Base – [decimal] Cannot be 0. Enter the exchange rate at the time the deposit was made. If the gift currency is the same as the base ledger, then exchange rate must be 1.

Validation Rules: Cannot be 0. If currency code above equals the currency of the active ledger, then exchange rate must equal 1.

Bank Cost Centre – [24ch.] The cost centre which is applied to the bank. Must be an active local posting cost centre for the ledger.

Validation Rules: Must be an existing entry in the cost centre table (a_cost_centre) for the active ledger with a_cost_centre_type_c = "Local" and a_posting_cost_centre_flag_1 = true. The user should be allowed to specify in the import dialog box that, in case of failure, a leading 0 should be added to the account (eg. "0300" instead of "300") and the lookup re-attempted.

Gift Type – [16ch.] Must be a valid gift type, "Gift", "Gift In Kind" or "Other".

Validation Rules: If blank, populate the field from MFinanceConstants.GIFT_TYPE_GIFT. If non-blank, must equal one of GIFT_TYPE_GIFT, GIFT_TYPE_GIFT_IN_KIND or GIFT_TYPE_OTHER (use the hard coded constants from Shared/lib/MFinance/Constants.cs, GIFT_TYPE_*)

Gift Record

Row Type - “T”

Donor Key – [Int64] The partner key of the donor. The donor must be entered as a partner before the gift batch is imported. Note that if the donors partner record has been merged into another partner, then the new partner key must be specified instead of the key of the merged record.

Validation Rules: Must be a valid key into the partner table, p_partner. However, if the partner status is "MERGED", then the new partner must have been used so the import will fail (ideally the new partner key that should have been used will be included in the error message).

Donor Short Name – This field is included for compatibility with the Gift Batch Export. It is not used on import.

Method of Giving Code – [16ch.] Select one of the options defined in the Method of Giving table for your installation.

Validation Rules: Must be an existing "a_method_of_giving_code_c" code in the Method of Giving table, a_method_of_giving.

Validation Rules: Must be a valid entry in the Motivation Detail table, (a_motivation_detail: a_motivation_detail_code_c, a_ledger_number_i = active ledger, a_motivation_group_code_c = motivation group code) and with status = true (a_motivation_status_1). The motivation detail recipient key (p_recipient_key_n) must match the recipient key on the import record if they are both non-zero.

Cost Centre Code – This field is included for compatibility with the Gift Batch Export. It is not used on import.

Gift Comment One – [160ch.] Optional. Long description of the gift.

Validation Rules - Cannot be more than 160 characters in length. No need to check for SQL Injection if the SubmitChanges DataAccess Methods are used as these always use Parameterized SQL queries. With that kind of SQL queries the Gift Comment One will be a Parameter of Type string to the SQL query and the RDBMS will never execute Query Parameters as SQL, hence SQL Injection cannot happen.

Gift Comment One Type – Optional. If used, must contain a valid Gift Comment Type. Cannot be blank if Gift Comment One is used.

Validation Rules: - blank (cannot be blank if Gift Comment One is not blank) or a valid GIFT_COMMENT_TYPE. See Shared/lib/MFinance/Constants.cs, GIFT_COMMENT_TYPE*. (Note: that Constant.cs file is actually missing more constants: Donor, Recipient, Office)
