• What is the cause and solution for SAP error message CX167 - Material type "&" is not allowed ?

  The SAP error message CX167, which states "Material type '&' is not allowed," typically occurs when you are trying to create or modify a material in SAP, and the specified material type is not permitted for the operation you are attempting to perform. This can happen in various contexts, such as during material creation, data migration, or when using specific transactions.
  Causes:
  
  Incorrect Material Type: The material type you are trying to use is not configured in the system or is not allowed for the specific transaction.
  Authorization Issues: The user may not have the necessary authorizations to create or modify materials of that type.
  Configuration Settings: The material type may be restricted in the configuration settings of the SAP system, possibly due to business rules or settings in the material master data.
  Transaction-Specific Restrictions: Certain transactions may only allow specific material types, and the one you are trying to use is not included.
  
  Solutions:
  
  Check Material Type: Verify that the material type you are trying to use is valid and exists in the system. You can do this by checking the configuration in the Material Master settings (Transaction Code: OMS2).

  Consult Configuration: If you have access, check the configuration settings for material types in the IMG (Implementation Guide) under Logistics > Material Master > Basic Settings > Material Types. Ensure that the material type is allowed for the intended operations.
  Use Allowed Material Types: If the material type is indeed restricted, consider using a different material type that is allowed for the operation you are performing.
