SI62SP1[Swift]Colon and Hyphen characters cause messages to NAK



Running SmartInvestigate 62SP1 and encountered an issue with SwiftMessage Validation. When a users sends SWIFT correspondence from Smart Investigate the message validation does not notice if a second line in a field content begins with a colon or hyphen character. Such a message is against SWIFT MT messaging standards so the message gets a NAK (Negative Acknowledgement).

Error Messages

None in PRPR / Smart Investigate. The message gets a NAK.

Steps to Reproduce

1) Create a Swift Correspondence of Type MT199
2) In Field 79, enter 2 lines of text in which the second line starts with colon or hyphen character. 
3) The validation does not occur. 

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules in 
Rule-Edit-Validate rule SWIFT79.


Provided HFix-9881 to address the reported issue.
