Folks
1) What's the correct way to check for an existence of a segment? So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:
request.GetValueAt("NTE(1):Description")'=""
Or in a DTL, to see if a Z segment exists:
source.{ZEF:Counter}=1
