Question -------- After successfully generating data from my outbound transaction set, I proceeded to change a mapping. My formulas generated without problems. Everything in my map appears to be OK. So, why am I not producing the entire segment any more for this one segment when I was generating that segment before (even though it was incorrect). Answer ------ The EDI person accidentally deleted the level value while mapping. Remember that levels only apply to outbound maps. Before you modify/delete the levels, make sure that you understand what the levels mean. Read the documentation for the Generate EDI Data, the Segment Override Maintenance and the Segment Maintenance functions for more information on transaction set levels. Levels have different meanings depending on the transaction sets involved.
