• What is the cause and solution for SAP error message M3317 - No external number assignment possible for mat. type & ?

  The SAP error message M3317, "No external number assignment possible for mat. type &", typically occurs when you are trying to create a material master record with an external number assignment for a material type that does not support it. This can happen during the creation of materials in the Material Management (MM) module.
  Cause:
  
  Material Type Configuration: The material type you are trying to use is configured to use internal number assignment only. In SAP, material types can be set up to allow either internal or external number assignment.
  Number Range Configuration: The number range for the material type may not be set up correctly, or it may be restricted to internal number assignment.
  User Settings: The user may have settings that enforce internal number assignment.
  
  Solution:
  
  
  Check Material Type Configuration:
  
  Go to the transaction code OMS2 to check the configuration of the material type.
  Look for the "Number Assignment" field and ensure that it is set to "External" if you want to use external number assignment.
  
  
  
  Adjust Number Range:
  
  If you need to change the number assignment method, you may need to adjust the number range settings.
  Use transaction code SNRO to check the number range object for the material type and ensure it is configured correctly.
  
  
  
  Use Internal Number Assignment:
  
  If the material type is set to internal number assignment, you can either change your approach to use internal assignment or create a new material type that allows external number assignment.
  
  
  
  User Profile Settings:
  
  Check the user profile settings to ensure that there are no restrictions on number assignment methods.
  
  
  
  Consult with SAP Basis or Configuration Team:
  
  If you do not have the necessary permissions to change the configuration, consult with your SAP Basis or configuration team to make the required changes.
  
  
  
  Related Information:
  
  Material Types: Different material types in SAP (e.g., raw materials, finished goods, trading goods) have different configurations and purposes.

  Transaction Codes:
  
  OMS2: To configure material types.
  SNRO: To manage number ranges.
  MM01: To create a new material master record.
