• What is the cause and solution for SAP error message WM077 - Internally issued no. & is within critical area of number range ?

  The SAP error message WM077 indicates that an internally generated number (such as a document number) is within a critical area of the number range. This typically occurs in the Warehouse Management (WM) module when the system attempts to generate a number that falls within a range that is reserved or restricted for certain operations.
  Cause:
  
  Number Range Configuration: The number range for the specific document type (like transfer orders, inventory documents, etc.) may be configured in such a way that certain numbers are reserved or restricted.
  Exhausted Number Range: The number range may be exhausted, and the system is trying to generate a number that is not available.
  Critical Area: The number being generated falls within a critical area that is reserved for specific purposes, such as system-generated documents or special transactions.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object for the document type you are working with (e.g., transfer orders).
  Check the configuration to see if there are any restrictions or if the number range is exhausted.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you may need to extend the number range or adjust the configuration to allow for more numbers to be generated.
  Ensure that the number range is not set to a critical area that prevents the generation of new numbers.
  
  
  
  Review Document Types:
  
  Check if the document type you are trying to create is correctly configured and not conflicting with other document types that may have reserved number ranges.
  
  
  
  Consult SAP Notes:
  
  Look for any relevant SAP Notes that may address this specific error message or provide guidance on number range issues.
