Hi, I 've been looking if there is a way to edit the list of error codes of X12 997 acknowledgment, Im using Biztalk Server 2006 I receive an error which says that the code value is invalid in AK403, i guess this is becuase the value that i Receive in this field is not in de error codes list , thats why I want to know if I can edit the list to add the value that I receive as a error code. Is this Possible?Thanks!!
