Storage Location Determination in BOM Explosion

Use

In order for the system to find the issue storage location for components in a BOM explosion in MRP or in a backflush in repetitive manufacturing, you can make the appropriate settings according to the assignment of storage locations in the plant.

Integration

The process flow for the storage location determination described here is the same as the process flow for supply area determination (if you use Kanban), thus only storage location determination is described below.

Prerequisites

  • In the BOM for the assembly or for the finished product, you have defined the production storage location for the component in the BOM item.

  • If you have not defined a production storage location in the BOM item, you can define in Customizing for MRP or in Customizing for Repetitive Manufacturing which strategy the system is to use to find the issue storage location and from which location the components are to be withdrawn in the BOM explosion. You do this in the IMG activity Define stor.loc./supply area determination for BOM explosion

Features

Production Storage Location in the BOM Item

If you have defined a production storage location in the BOM item for the withdrawal of the components, the system finds it during the BOM explosion and adopts it in the planning run. You can check it in the component overview for the planned order.

No Customizing Strategy, No Production Storage Location in the BOM Item

If you have not entered a production storage location in the BOM item nor defined a strategy in Customizing, the system checks whether the production storage location has been maintained in the material master for the component and uses it as the issue storage location in the BOM explosion.

Customizing Strategy, No Production Storage Location in the BOM Item

If you have determined a strategy in Customizing and if no storage location has been defined, the system reads the MRP group for the assembly and determines the strategy for the storage location determination. The following strategies are available:

  • If you set indicator 1 Only components (or no indicator) in Customizing, the system checks to see whether the production storage location has been maintained in the material master of the components and uses this as the issue storage location.

You use this strategy if you always withdraw one particular component from the same storage location.

  • If you set indicator 2 Only assembly , the system checks to see whether the proposal issue storage location has been maintained in the production version of the assembly or finished product. If this has been maintained, the system uses this issue storage location for all components of the BOM for the assembly or finished product.

If no proposal issue storage location has been maintained, the system adopts the receiving storage location of the assembly or finished product. The system then uses the receiving storage location as the issue storage location for the components.

You can define the receiving storage location in the production version of the assembly in the To location field or in the material master of the assembly or finished product in the Production storage location field.

You use this strategy if you work with repetitive manufacturing and all components lie together in one storage location close to the production line where they are required.

  • If you set indicator 3 , the system then proceeds as with indicator 1. If it does not find a storage location, it then proceeds as with indicator 2.

  • If you set indicator 4 , the system then proceeds as with indicator 2. If it does not find a storage location, it then proceeds as with indicator 1.
