Oddity reading 835 documents via the X12 file reader

[Lawrence H. Harris]

I have just setup a simple process using the EnsLib.EDI.X12.Service.FileService to read an document formatted as:

 

ISA GS ST-SE ST-SE ST-SE GE IEA

 

The category is 835=835_X091

The Target Config Name is 'Process X12 835 B' and there is no Reply Target Config Name

Batch handling is single session batch

 

The Operation 'Process X12 835 B' is EnsLib.EDI.X12.Operation.FileOperation

AutoBatchParentSegs is false

 

What I see is that I get 5 messages

 

Message 1 is the first ST-SE, Message 2 is the second ST-SE, Message 3 is the third ST-SE

Message 4 is the GS ST-SE ST-SE ST-SE GE (the input minus the ISA/IEA)

Message 5 is just a copy of the whole input.

 

I guess I can pass this to a message router to filter out messages 4 and 5 but is there any way to tell it I only want the 3 enclosed transactions?  I seemed to me that asking for Single Session Batching would break out each transaction.

 

I tried using BatchHandling set to individual with no apparent difference.

 

If I define ReplyTargetConfigNames as 'Process X12 835 A' then I get one additional file containing just an ISA/IEA with no contents.

 

Thanks, Lawrence
