Production Planning and Control for Repetitive Manufacturing 

In this section, a description is given of the special features for planning the assembly order in the planning table as well as posting the goods receipt for the assembly/planned order. If you require more information on production planning and control using repetitive manufacturing, please refer to the SAP documentation PP Repetitive Manufacturing.

If the material to be planned has been flagged for repetitive manufacturing and has been assigned a repetitive manufacturing profile in the material master record, you can carry out capacity planning and you can assign the assembly order to production lines in the planning table of repetitive manufacturing.

You can also carry out capacity planning for the assembly/planned order from the main menu of capacity planning or from the current stock/requirements list. For more information on capacity planning, please refer to the SAP documentation PP Capacity Planning.

You post the goods receipt for the assembly/planned order using a special function in the main menu of repetitive manufacturing.

Processing Assembly Orders in the Planning Table From the Material View

Make-to-order production is used for assembly orders and stock is managed individually for each sales order. Therefore, the following functions are not available for planning production quantities over several periods:

It is also not possible to carry out a distribution according to a daily rate as new planned orders are created for each day in this function. This does not make sense for assembly processing.

You can only process one assembly order at a time.

To process the assembly order in the planning table from material view, proceed as follows:

  1. Starting from the main menu of repetitive manufacturing, select RS quantities ® Create and change.

    2. The system branches to the initial screen of the planning table.

  2. Enter the plant, select the material view, and press Choose.

    3. The system displays the dialog box entitled, Selection Data.

  3. Enter the material number and the period of examination.

Changing Dates or Quantities in Assembly Orders

To change either the quantity or a date in an assembly order, proceed as follows:

Double-click the mouse on the corresponding period.

You can then make the necessary changes in the screens that follow.

 

Assigning Assembly Orders to Production Lines

Assembly orders can only be assigned to the production line one at a time. To do this, proceed as follows:

  1. Position the cursor on the assembly order.
  2. Select Edit ® Assign quantities ® For one period.

    3. The system displays the dialog box entitled, Detailed Data for Assignment.

  3. Select the production version or the production line on which the product is to be produced.

 

Capacity Planning

Capacity planning is carried out as in repetitive manufacturing without make-to-order. For more information on this, please refer to the SAP documentation PP Repetitive Manufacturing.

 

GR Posting for the Assembly Order

To post the goods receipt for the assembly order, proceed as follows:

  1. Starting from the menu screen of repetitive manufacturing, select Backflush ® Final backflush.

    2. The backflushing screen appears.

  2. Enter the following data here:

    3. Posting date

    The system proposes the current date as the posting date. It uses this date to determine the BOM of the assigned planned order. If no further planned order exists for the sales order, the system explodes the BOM that is valid on this date.

    Document date

    The system proposes the current date as the document date. Check this date.

    Plant

    Enter the plant for which you want to carry out the goods receipt for the sales order.

    Sales order

    The system uses the sales order to determine the planned orders.

    If only one planned order is assigned, it is automatically proposed in the appropriate field by the system once you have selected Enter. The system also proposes the planned order quantity in the Backflush quantity field.

    If several planned orders exist for the sales order, then the system displays a dialog box once you have selected Enter. Here, you must select the planned order for which you want to carry out the goods receipt. Then the system enters this planned order in the appropriate field and proposes the planned order quantity in the Backflush quantity field.

    If no further planned orders exist for this sales order as the quantity has already been produced, but you still want to carry out a goods receipt (overdelivery), the system explodes the BOM that is valid for the current date.

    Sales order item

    If a sales order contains several materials, you must enter the sales order item as well as the sales order number. Then, the system proposes the material for which the goods receipt is to be posted automatically once you have selected Enter as well as the planned order quantity.

  3. Now you have two options:

    4. – Save the data here.

    – Or, to avoid posting errors and to check component data, press Execute. You then branch into the component overview screen where you can make any necessary corrections or you can also carry out the availability check. Save your data.

  4. In the background, the system explodes the BOM, posts the goods movements on the basis of the BOM explosion, reduces planned orders or run schedule quantities, and updates costs and statistics.

Backorder postings from backflushing are not possible here as the postings are not carried out on the basis of a run schedule header.
