• What is the cause and solution for SAP error message GMMASTERDATA091 - Number assignment failed; grant not created ?

  The SAP error message GMMASTERDATA091, which states "Number assignment failed; grant not created," typically occurs in the context of Grant Management (GM) within SAP. This error indicates that the system was unable to assign a unique number to a grant, which is necessary for its creation.
  Causes:
  
  
  Number Range Issues: The most common cause is that the number range for grants is either not defined, exhausted, or incorrectly configured. If the system cannot find an available number in the defined range, it will throw this error.
  
  
  Authorization Issues: The user may not have the necessary authorizations to create a grant or access the number range.
  
  
  Configuration Errors: There may be issues in the configuration of the Grant Management module, such as incorrect settings in the number range object.
  
  
  System Locking: Sometimes, if the system is locked or if there are issues with the database, it may prevent the number assignment.
  
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Look for the number range object related to grants (usually GRANT or similar).
  Ensure that the number range is defined and that there are available numbers in the range. If the range is exhausted, you may need to extend it.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you can create a new number range or extend the existing one. This can be done in the transaction code OAVN (for number range maintenance).
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to create grants and access the number range. This can be checked in transaction SU53 or by reviewing the user's roles and authorizations.
  
  
  
  Review Configuration:
  
  Check the configuration settings for Grant Management in the SPRO (SAP Project Reference Object) transaction. Ensure that all settings related to grants and number ranges are correctly configured.
  
  
  
  System Check:
