• What is the cause and solution for SAP error message GL301 - No unblocked sequence available ?

  The SAP error message GL301: No unblocked sequence available typically occurs in the context of General Ledger (GL) accounting when trying to post a document. This error indicates that the system cannot find an available document number in the specified number range for the posting. Here are the causes, solutions, and related information for this error:
  Causes:
  
  Exhausted Number Range: The number range for the document type you are trying to use has been exhausted, meaning all available numbers have been used up.
  Blocked Number Range: The number range may be blocked for posting, either due to configuration settings or because it has been set to not allow new postings.
  Incorrect Configuration: The number range configuration for the document type may not be set up correctly, or the number range may not be assigned to the correct company code or fiscal year.
  Document Type Issues: The document type you are using may not have a valid number range assigned to it.
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object (e.g., FBN1 for financial documents).
  Ensure that the number range is correctly defined and that there are unblocked numbers available.
  
  
  
  Extend Number Range:
  
  If the number range is exhausted, you may need to extend it. This can be done in transaction code OBA7 (Maintain Number Ranges for Document Types).
  Increase the upper limit of the number range or create a new number range if necessary.
  
  
  
  Check Document Type Assignment:
  
  Ensure that the document type you are using is correctly assigned to the number range in the configuration settings.
  You can check this in transaction code OBY6 (Assign Document Types to Number Ranges).
  
  
  
  Unblock Number Range:
  
  If the number range is blocked, you may need to unblock it in the configuration settings. This can be done in the same transaction code used for maintaining number ranges.
  
  
  
  Consult with SAP Basis or Functional Team:
  
  If you are unsure about making changes to the number range configuration, consult with your SAP Basis or functional team for assistance.
