BizTalk 2009/incorrect GlobalBusinessActionCode element in BTARN
There is a known issue on BTARN 3.3 that business document description may be incorrectly written in to 3A4 confirmation message's GlobalBusinessActionCode field. This happens when the following field is empty in original 3A4 message.
The following is the dedicated hotfix of this issue for BTARN 3.3. However we confirmed the same problem also exists on BTARN for BizTalk 2009 but the hotfix in the KB article applies to BTARN 3.3 only.
FIX: BTARN 3.3 intermittently writes incorrect values to the GlobalBusinessActionCode element when you use BTARN 3.3 to process RNIF messages
