Interunit Accounting Entries
When you create accounting entries by using the Pending Group Generator Application Engine process (AR_PGG_SERV) for interunit transactions, the accounting entries that are for the general ledger business unit that initiates the interunit entries inherit the document type from the transaction itself. For interunit accounting entries, the posting process automatically assigns document sequence numbers by using this document type.
However, the accounting entries for the other general ledger business units that are involved in the interunit transaction have blank values in the document type, document sequence number, and document sequence date fields. The Journal Generator process fills in the document sequence values for entries in the other general ledger business units.
