Not in 4.6. But you can have rule not persist the content of the X12 Group and/or X12 NNNN YYY transaction set. But the bizdoc envelope still gets created in the TN DB.
We have it configured to not persist the group content. We persist the interchange and transaction sets and have separate rules for each. The rule for the interchange does the 997 generation while the transaction set rule does the processing of the 810, 850, etc. for translation and sending to wherever.
I believe the wM6 EDITPA provides the ability to specify how far down to split an EDI doc and what to do with each of the pieces.
