You need to be able to identify the records in the file using the Tag Identifier field.
I have a schema that will parse you example.
Basically you add a positional Record that is maxOccurs=unbounded and declare each positional field. You can use the \”Allow early termination\” if the last field if the record terminates early.
After this Record declare another record called EndofFile. Set the Tag Identifier as EOF[space].
Email me if you would like the schema, it’s too big to post here.
