• What is the cause and solution for SAP error message WM079 - No more numbers are free in number range 01 ?

  The SAP error message WM079 ("No more numbers are free in number range 01") typically occurs in the Warehouse Management (WM) module when the system runs out of available numbers in a specified number range. This can happen during various processes, such as creating transfer orders, stock transport orders, or other warehouse-related documents.
  Cause:
  The error is caused by the exhaustion of the number range defined for a specific document type in the Warehouse Management system. Each document type in SAP is assigned a number range, and if all the numbers in that range have been used, the system will not be able to generate new document numbers, leading to this error.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check the Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Enter the object name related to the document type that is generating the error (e.g., WM for Warehouse Management).
  Check the number range intervals defined for the object and see if the current interval is exhausted.
  
  
  
  Extend the Number Range:
  
  If the number range is exhausted, you can extend it by creating a new interval or increasing the upper limit of the existing interval.
  This can be done in the same SNRO transaction by selecting the appropriate number range and modifying it.
  
  
  
  Check for Number Range Assignments:
  
  Ensure that the document type you are working with is correctly assigned to the number range in the configuration settings.
  You can check this in the configuration settings under SPRO -> Logistics Execution -> Warehouse Management -> Transfer Order -> Define Number Ranges.
  
  
  
  Reset the Number Range (if applicable):
  
  If you are in a testing environment and the number range is not needed anymore, you can reset it. However, this is not recommended in a production environment as it may lead to data inconsistencies.
  
  
  
  Monitor Usage:
  
  Regularly monitor the usage of number ranges to prevent running out of numbers in the future. You can set up alerts or reports to notify you when the number range is nearing its limit.

  By following these steps, you should be able to resolve the WM079 error and ensure that your warehouse management processes continue smoothly.
