Here is my edi message:

When I try to serialize it into my class:

}`

I have inside FTXSegments only the second row: FTX+WHI+++CN:9404219000
And LOCSegments is NULL.

Why? What is the problem and how to fix it?

Thank you,

Start with the EdiSegmentGroup attributes on FTXSegments and LOCSegments and compare their SequenceEnd values with the sample message's segment order. Trace how EdiSegmentGroup processes the FTX and LOC entry points, then reproduce the model serialization and verify that all FTX entries and the LOC group are populated.
