X12 Reference Value Overwritten by Bots

[djfurman]

When pulling a reference value from the transaction's ta_info reading, the ISA-ISA13 value (ISA transaction control number value) is overwritten by bots making it very difficult to access from originating envelope.

This should be fixed to the reference value for incoming files and refer to the table value in out transaction for the unique key created by the hash of ISA-ISA06 and ISA-ISA08.

If a workaround is needed - add envelope scripting or add a query to the x12.py file to specifically pull the value.
