Define stor.loc./supply area determination in BOM explosion

In this step, you define the strategy the system uses to find the storage location (issue storage location) for the components in BOM explosion, when backflushing and in MRP. This logic is also used in supply area determination.

In BOM explosion, the system tries to find a storage location in the BOM item (component). If no issue storage location has been defined in the BOM item, the system reads the MRP group that has been maintained for the assembly or the finished product and thus determines the strategy to use for storage location (supply area) determination.

Here, the system proceeds as follows:

• If you set indicator 1 Only components, the system checks to see whether the issue storage location has been maintained in the material master record of the components and uses this storage location. This storage location is then used as the withdrawal storage location and is displayed in the component list of the planned order.

You use this procedure for detemining the withdrawal storage location if you always withdraw one particular component from the same storage location. That is, every component is used at a specific storage location in the plant.

• If you set indicator 2 Only assembly, the system checks to see whether the proposal withdrawal location has been maintained in the production version of the assembly or finished product. If this has been maintained, the system uses this withdrawal storage location for all components and displays it in the components list in the planned order. If no proposal withdrawal location has been maintained, the system uses the assembly’s receiving storage location as the withdrawal storage location for the components. You can define the receiving storage location in the production version of the assembly in field To location or in the material master record of the assembly in field Issue stor.location.

If neither of these entries has been maintained, you can enter the receiving storage location (goods receipt storage location) in the backflush transaction in Repetitive Manufacturing which is then used as the withdrawal storage location for the components.

You should use this procedure when all components lie together in one storage location close to the production line where they are required.

• If you set indicator 3, the system first proceeds as for indicator 1 described above. If it cannot find a storage location using indicator 1, it then proceeds as described above for indicator 2.

• If you set indicator 4, the system first proceeds as for indicator 2 described above. If it cannot find a storage location using indicator 2, it then proceeds as described above for indicator 1.

Standard settings

No entry is delivered in the standard system. The system searches as described for indicator 1. That is, it searches for the issue storage location in the material master record of the compoennts.

Activities

Define the strategy to determine the issue storage location or supply area of the components per plant and MRP group.

Further notes

The same strategies are used to find the supply area. You can maintain the supply area in the same places as you can the issue storage location.

Use :

• In KANBAN, the supply area is relevant if you use the automatic kanban calculation. In the kanban calculation, the system only uses dependent requirements that refer to a supply area. Therefore, you must have maintained a supply area in either the BOM item, in the material master record or in the production version so that the system can find it in the planning run. In BOM explosion, the supply area of the components can also be determined using the logic of the supply area determination.

• If you work with Warehouse Management, you use the supply area to be able to determine the storage bin in production (usually close to the production line) where the components are provided and withdrawn for production. You assign the material and the supply area to the storage bin in the control cycles.
