I was able to remove the extra line feed in the custom flat file disassembler. But then I started getting another error. Biztalk was throwing an error while validating the instance.
The main problem is that the records in my flat file don't have any tag identifiers. If the MaxOccurs property for a repeating record is unbounded then I think tag identifiers are mandatory. Only then can Biztalk identify what type of record it is.
Now I've got 3 options
1. Tell the client to add tag identifier
2. Add tag identifiers in the custom flat file dissasembler
3. Remove the trailer record in the custom flat file dissasembler.
I leaning towards the 2nd option.
If anyone wants a code sample on how to modify the file in a custom flat file disassembler, let me know.
Thanks,
