 Plan Material Requirements for Detached Order Assemblies Locate this document in the navigation structure

Use

This procedure describes how to handle detached order assemblies in MRP: You can plan and manufacture them but still change the multi-level BOM for the sales order item. You can settle the quantity of assemblies already produced against the quantities still to be produced when you integrate the order assembly in the BOM at a later date and you have finished creating the BOM.

Prerequisites

  • You have created a sales order and a sales order item.

  • You have created a detached order assembly with an order BOM for the sales order item.

Caution Caution

You can also use any assembly with a material BOM, which means without an order BOM, as a detached order assembly. The system runs MRP correctly for this assembly but the assembly is not displayed in the order browser. This means that Engineering and Design cannot use the assembly for changes to the BOM.

End of the caution.

  • You have selected the strategy group Planning at assembly level (strategy 70 in the standard SAP System) in the material master for the header material of the order assembly. You have also set the mixed MRP indicator, selected a consumption mode , and entered a consumption period .

For further information on this planning strategy, see Planning at Assembly Level (70) in Demand Management (PP-MP-DEM).

Procedure

  1. Starting from the Demand Management node, choose   Planned Independent Requirement   Create   . Enter the material number for the header material of the order assembly and the plant or the MRP area. Click   ( ) .

  1. Enter the planned independent requirement.

  1. Assign the account for the planned independent requirement to the sales order and the sales order item:

  1. Choose   Goto   Additional data.  

  2. The Indep. Reqmts: Additional Data dialog box appears.

  3. Select category E, customer individual requirement , as the account assignment category . Click ( ) and enter the number of the sales order and the sales order item. Click ( ) and ( ) .

You can use ( ) next to the Acct. assmt cat. field in the Indep. Reqmts: Additional Data dialog box to check the account assignment data at any time.

The accounts for the planned independent requirements for the order assembly are now assigned to the sales order. These planned independent requirements can be settled against the dependent requirements for the sales order when the assembly is integrated in the multi-level BOM for the sales order item.

  1. Starting from the MRP node, choose   Planning   Single-Item, Multi-Level   . Enter the material number for the header material of the order assembly and the MRP and process parameters. Click   ( ) twice.

The system uses the account assignment to the sales order item and thus selects and explodes the order BOM for this material, when there is one. The system displays the runtime statistics for the planning run.

  1. Starting from the MRP node, choose   Evaluations   Stock/Reqmts List   . The header material for the order assembly is the default material number. Click   ( ) twice.

The system displays the stock/requirements list for the material. The MRP elements are displayed in a separate individual customer segment.

Result

The system has generated planned independent requirements on assembly level (requirements type VSFB) for the header material of the detached order assembly. The system has assigned the accounts to the sales order item for the sales order. The system then generated planned orders or purchase requisitions to cover these planned independent requirements in the MRP run.

You can convert the planned orders to production orders and the purchase requisitions to purchase orders, thus triggering production and external procurement for this order assembly.
