When a receipts list is generated, it is added to the Receipts list journal. If an applicable document flow with direction 'Outbound' and type 'Receipts list' exists, also a record is added to the Outbound message queue. When this record is processed, the 'Warehouse - Receipts list to XML' message is run. As a result, this message gets the data from the journal as defined in the outbound message queue record. With this data, it creates and sends an EDI receipts list message file to the 3PL warehouse to inform them on the expected receipt.
