• What is the cause and solution for SAP error message WW120 - MG materials can only be maintained in SAP Retail clients ?

  The SAP error message WW120 indicates that the materials classified as "MG" (which typically refers to merchandise or retail materials) can only be maintained in SAP Retail clients. This error usually arises when a user attempts to create or modify a material that is designated for retail in a non-retail SAP client.
  Cause:
  
  Client Type: The user is working in a non-retail client (e.g., a standard SAP ERP client) where the functionality for managing retail-specific materials is not available.
  Material Type: The material type being used is specifically designed for retail operations, which are only supported in SAP Retail environments.
  Configuration Issues: There may be configuration settings that restrict the maintenance of certain material types to specific client types.
  
  Solution:
  
  Switch to a Retail Client: If you need to maintain MG materials, you should log into an SAP Retail client where these materials can be managed.
  Check Material Type: Ensure that the material type you are trying to create or modify is appropriate for the client you are using. If you are in a non-retail client, consider using a different material type that is supported.
  Consult with SAP Basis or Configuration Team: If you believe you should be able to maintain these materials in your current client, consult with your SAP Basis or configuration team to check if there are any settings that can be adjusted or if there is a need for a different client setup.
