| Sequence numbers in Purchase Control (PUR) |  |
| Sequence numbers are used as follows in Purchase Control: When an Order Line is generated in the Purchase Order Lines (tdpur4101m000) session, the purchase order line's sequence number is one. When the relevant order line is split, or a back order is generated for the order line, the order line changes to a Total line in the Purchase Order Lines (tdpur4101m000) session with a sequence number of zero. The linked line details of line type Detail or Back Order in the Purchase Order Line Details (tdpur4101m200) session, have a sequence number greater than zero. Example Adding an order line:
Sequence number | Order quantity | Planned delivery date
1 | 100 | 14/12
Splitting of the order line:
Sequence number | Order quantity | Planned delivery date
0 | 100 | 14/12
1 | 80 | 14/12
2 | 20 | 21/12
Assume that you must modify the order quantity. The sum of the order quantities can be lower than the total order quantity. If you save the order line, the total order quantity is updated. After receipts are performed:
Sequence number | Order quantity | Planned delivery date | Delivered quantity | Back order quantity
1 | 80 | 14/12 | 70 | 10
2 | 20 | 21/12 | 0 | 0
3 | 10 | 28/12 | 10 | 0
Sequence number 3 is of the Back Order line type. You must evaluate the back order quantity. If you agree upon a back order, you can specify a delivery date for this back order. If for that delivery date a sequence number already exists, the back order quantity is added to the order quantity of the concerning date. If for the specified date an order quantity is not yet specified, a new sequence number is created. ERP LN also checks if the delivery address and the ship-from address match.
