I am trying to migrate some positional flat file schemas from Seeburger to BizTalk and it seems I am stuck with a problem I do not know how to handle with BizTalk.
I'll try to reduce the complexity to the basic issue I am having.
Let's say that in Seeburger the following message is processed.
Field1----Field2-------Field3----Field4--[CR][LF]
I added padding character "-" here to be visible, and CR LF segment terminator
The seeburger schema has defined the following structure for the above message
Field1 = Min/Max length = 10 characters
Field2 = Min/Max length = 13 characters
Field3 = Min/Max length = 10 characters
Field4 = Min/Max length = 8 characters
All fields are optional so it may be possible to get a message like this only
Field1----Field2-------Field3----[CR][LF]
Until here everything works fine. The problem is that the actual messages received by Seeburger are looking like this for example:
Field1----Field2-------Field3----Field4[CR][LF]
or
Field1----Field2-------Field3[CR][LF]
Please notice that the padding characters are missing from the last element from the record. Seeburger knows to handle this but in BizTalk I am not able to validate a message like this. ( without last element length < length defined in schema )
Biztalk expects that the length of last field from the record to be the defined length in the schema which makes sense. I did tried a lot of things but I was not able to find a solution for this.
Was somebody else stuck on this or do you have any suggestions?
