Is It Mandatory to Extend Material in MMSC for Moving Stock to Multiple Storage Locations?

Question:

Is it mandatory to extend material in MMSC when transferring stock to multiple storage locations?

Answer:

Yes, it is mandatory to extend the material in MMSC for the storage location where you want to transfer the stock.

Why Is It Necessary?

When receiving stock at a specific storage location, the system needs to recognize that the material is extended to that location. Without this extension, the system will not allow stock movement to the target storage location. There are two ways to extend the material master to a new storage location:

Using MMSC – Recommended for mass storage location extensions.
Using MM01 – Can also be used for manual extension of material master data.

Storage Location Customization in SAP

The requirement to extend materials manually in MMSC depends on your system configuration.

Some SAP configurations allow automatic creation of storage location segments during the first stock movement.
If automatic creation is disabled, you must extend the material manually using MMSC or MM01.

Configuration Steps for Automatic Storage Location Creation

To enable automatic creation of storage locations, configure the following settings in SAP IMG:

1. Goods Receipt Configuration:

Path: IMG -> Materials Management -> Inventory Management -> Goods Receipt -> Create Storage Location Automatically

2. Goods Issue Configuration:

Path: IMG -> Materials Management -> Inventory Management -> Goods Issue -> Create Storage Location Automatically

3. Automatic Movements Configuration:

Path: IMG -> Materials Management -> Inventory Management -> Automatic Movements -> Create Storage Location Automatically

Key Takeaways

Manual extension is mandatory if automatic creation is disabled.
Automatic storage location creation can be configured using movement types.
MMSC or MM01 can be used for manual extension of materials to storage locations.
