• What is the cause and solution for SAP error message GMMASTERDATA145 - Grant type &1 does not allow internal number assignment ?

  The SAP error message GMMASTERDATA145 indicates that there is an issue with the grant type configuration in the Grants Management module. Specifically, it states that the grant type you are trying to use does not allow for internal number assignment. This typically occurs when you are trying to create or manage grants and the system is unable to automatically assign a number to the grant due to the settings associated with that grant type.
  Cause:
  
  Grant Type Configuration: The grant type you are using is configured to not allow internal number assignment. This could be due to the settings in the configuration of the grant type in the SAP system.
  Number Range Assignment: The number range for the grant type may not be set up correctly, or it may be set to external number assignment, which means that users must manually enter the grant number instead of the system generating it automatically.
  Authorization Issues: There may be authorization issues preventing the system from assigning a number.
  
  Solution:
  
  
  Check Grant Type Configuration:
  
  Go to the configuration settings for Grants Management (Transaction code: SPRO).

  Adjust Authorization Settings:
  
  Ensure that the user has the necessary authorizations to create grants and that there are no restrictions that would prevent the system from assigning a number.
