Creating the Batch Header Segment
The batch header segment is a positional segment that contains the Sender ID and Receiver ID. Each file can have only one batch header segment.
Note: For inbound transmissions, you must map the Batch Number
field in the batch header. This is necessary because you must use
the same value in the Batch Response Header segment.
Use this procedure to create the batch header segment in the NCPDP side of a map.
