• What is the cause and solution for SAP error message MIMA253 - Number range &1 is designated as external or does not exist ?

  The SAP error message MIMA253 indicates that there is an issue with the number range that is being used in a particular transaction or process. Specifically, it states that the number range you are trying to use is either designated as "external" (which means it is not managed by the system but rather by the user) or it does not exist in the system.
  Causes:
  
  Non-Existent Number Range: The number range you are trying to use has not been defined in the system.
  External Number Range: The number range is set to external, meaning that the system does not automatically assign numbers; instead, the user must manually enter them.
  Configuration Issues: There may be a misconfiguration in the number range settings for the specific document type or object you are working with.
  Authorization Issues: The user may not have the necessary authorizations to access or use the specified number range.
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object and check if the number range is defined and active.
  If it does not exist, you may need to create a new number range or adjust the existing one.
  
  
  
  Adjust Number Range Settings:
  
  If the number range is set to external and you want the system to manage it, you can change the settings to internal.
  This can be done in the same SNRO transaction by editing the number range intervals.
  
  
  
  Create a New Number Range:
  
  If necessary, create a new number range for the relevant object. Ensure that it is set up correctly (internal or external as per your requirements).
  
  
  
  Check User Authorizations:
  
  Ensure that the user has the necessary authorizations to use the number range. This can be checked in the user roles and profiles.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or help files related to number ranges for specific guidance on your scenario.
