Sequence numbers on purchase orders

Sequence numbers are used as follows:

  • 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 Backorder in the Purchase Order Line Details (tdpur4101m200) session, have a sequence number greater than zero.
Example

Adding an order line:

Sequence numberOrder quantityPlanned delivery date
110014/12

 

Splitting of the order line:

Sequence numberOrder quantityPlanned delivery date
010014/12
18014/12
22021/12

 

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 numberOrder quantityPlanned delivery dateDelivered quantityBack order quantity
18014/127010
22021/1200
31028/12100

 

Sequence number 3 is of the Backorder 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. LN also checks if the delivery address and the ship-from address match.
