 Increasing the Sales Order Quantity

Purpose

The customer may want to increase the order quantity after you have already checked and saved the sales order. The process describes how the system proceeds when you increase the order quantity in the sales order and do not use the Recreate Receipt Elements function in the process.

Process

  1. You increase the quantity of a sales order.

  2. The change is transferred to SAP APO. In most cases, ATP Customizing is set so that SAP APO first carries out an availability check. The availability check finds the already existing planned order.

  3. To plan the missing remaining quantity, production planning and detailed scheduling is invoked. The system creates a new (temporary) planned order to cover the missing quantity.

  4. Using the results of the availability check and the subsequent production planning, the system creates a delivery proposal.

  5. After the sales order has been saved in R/3, the change to the sales order is also saved in SAP APO.

  6. In SAP APO, after the change to the sales order has been posted, planning is retriggered for the end product on the basis of the planning procedure set ( planning procedure 3, “Cover Dependent Requirements Immediately” ).

    Depending on your settings and the selected procedure, this new planning run may change the receipt elements again. Depending on the heuristic used, this may lead to undesired side effects if lots are grouped together. This is the case, in particular, in finite scheduling and/or when important components are taken into account ( planning procedure 1, manual with check ) if complete delivery is desired If complete delivery is desired, in certain circumstances, new dates/times are calculated in planning due to the grouping of lots.

    Note Note

    To avoid the grouping of lots in downstream planning processes, use the heuristic SAP_PP_CTP Planning of Material Shortage Quantities for CTP . The advantage of this heuristic is that in subsequent planning processes, the receipt elements are reused even if they are not suitable from a lot size viewpoint.

    This heuristic is already assigned to planning procedure 3 as standard. That is, if you assign this standard planning procedure to the finished product and the important components, you can avoid the side effects of lot-size groupings.

    End of the note.
