MMSC Usage and MRP IndicatorSAP's MMSC transaction code (TCode) is widely used to extend materials to storage locations within a plant. Additionally, the MRP indicator in MMSC plays a crucial role in defining whether stock from a particular storage location should be considered in Material Requirements Planning (MRP). In this guide, we will cover:
What is the Use of MMSC?Function of TCode MMSCThe MMSC transaction code is used to extend a material to the storage locations view that are maintained for a plant. This eliminates the need for manually assigning a material to multiple storage locations, making the process efficient and error-free.How It Works
Benefits of MMSC
MRP Indicator Deletion in MMSCUnderstanding the MRP Indicator in MMSCThe MRP (Material Requirements Planning) indicator in MMSC controls whether stock in a particular storage location is considered during MRP runs. If the Exclude from MRP option is set, the stock from that location will not be included in MRP calculations.Issue: Removing the MRP Exclusion Indicator in MMSCA common issue users face is that once the Exclude from MRP indicator is set for a storage location in MMSC, it becomes a greyed-out (non-editable) field, preventing users from removing or modifying it directly.Solution: How to Remove the MRP Exclusion IndicatorSince MMSC only allows the creation of entries and does not support modifications, the following alternatives can be used:Method 1: Using TCode MM02
Method 2: Mass Update Using TCode MM17For bulk updates, use TCode MM17 to modify the MRP indicator for multiple materials and storage locations at once.Final ThoughtsUnderstanding how to use MMSC and manage the MRP indicator effectively can significantly improve inventory and planning accuracy in SAP. While MMSC is great for extending materials to storage locations, modifications such as removing the 'Exclude from MRP' indicator must be done using MM02 or MM17.By leveraging these SAP transaction codes correctly, businesses can ensure a smooth and optimized material management process while keeping MRP calculations accurate. Frequently Asked Questions (FAQs)1. What is the difference between MMSC and MM02?
2. Can I delete a storage location using MMSC?No, MMSC does not support deletion. You can only extend materials to storage locations.3. What happens if I exclude a storage location from MRP?If the Exclude from MRP option is enabled, the stock in that storage location will not be considered in MRP runs.4. How can I remove the MRP exclusion for multiple materials at once?Use TCode MM17 to perform a mass update of the MRP indicator across multiple materials and storage locations.5. Can I edit the MRP indicator directly in MMSC?No, once set, the MRP indicator in MMSC becomes greyed out. You need to use MM02 or MM17 to modify it.6. Does MMSC impact MRP planning directly?MMSC itself does not control MRP planning but determines which storage locations are extended for a material. The MRP indicator in MMSC influences whether stock from a location is considered in MRP.
