Can't process a message that contains Field 77A in Swift Message Pack

Symptoms

When you use the BizTalk Server Accelerator for SWIFT Message Pack to process a valid FIN message of type MT 300, a parsing error occurs, and the processing operation fails. This error occurs when Field 77A is present and its content is in an unstructured format.

Cause

This issue occurs because the schema file for MT 300 enforces a structured format for Field 77A.

Cumulative update information

The fix that resolves this issue is included in Cumulative Update 2 for SWIFT Message Pack 2015.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information

The following change was made to address this issue:
  • The schema complex type that defines the MT 300 Field 77A was updated to allow an unstructured format. Before the change, line 1 of Field 77A was required to start with text that matches the following regular expression: 

    /[A-Z]{1,8}/ 

    After the change, line1 can be any text that complies with the SWIFT "x" character set.

The following table shows the file that's updated to resolve this issue and which is included in Cumulative Update 2 for Message Pack 2015.

File nameInstallation path
SWIFT Base Types.xsd[Install Dir]\SWIFT Messages\A4SWIFT-SRG2015\Base Schemas\

Notes
  • The default installation path (the Installation directory) is: C:\Program Files (x86) \MP2015\.
  • After you install Cumulative Update 2, you may have to update, rebuild, and redeploy any BizTalk applications that have dependencies on these files.
