A Partner Return file consists of batches of records that did not meet the Partner Company’s record edits. These records will have been outcollected by your company (the Company Carrier) and sent to the Partner by the ARP. The returned records are in batches with a new batch sequence number, not the sequence number from the original batch; however, each record contains the original batch sequence number.
The reason for a new batch sequence number is because the returned batch can contain records from multiple batches. That is why each CIBER record (not including all Header and Trailer) contains the original batch sequence number. This allows for mapping returned records back to the original batch.
Partner Return files are placed in the Incollect "In" directory, just like a new Incollect file, and processed correctly by the IDI Clearinghouse Service.
The Clearinghouse Service determines the original Outcollect batch(es) that included the rejected records. If the original Outcollect cannot be found, the batch cannot be processed and is written to an error file which also notifies the appropriate person of the error.
The returned records are added to the Return Summary.
