• What is the cause and solution for SAP error message AM157 - Last address number in number range issued; reorganization necessary ?

  The SAP error message AM157 ("Last address number in number range issued; reorganization necessary") typically occurs when the number range for address numbers in the Asset Management module has been exhausted. This means that the system has issued all available numbers in the defined range, and no new address numbers can be generated until the range is reorganized.
  Cause:
  
  Exhausted Number Range: The number range defined for asset addresses has been completely utilized.
  Configuration Issues: The number range may not have been set up correctly, or it may be too small for the volume of transactions being processed.
  Lack of Reorganization: If the system has not been reorganized for a long time, it may lead to this issue.
  
  Solution:
  To resolve the AM157 error, you can take the following steps:
  
  
  Reorganize the Number Range:
  
  Go to the transaction code SNUM (Number Range Maintenance).
  Find the relevant number range object for asset addresses (usually ANR for asset numbers).
  Check the current status of the number range and see if it needs to be reorganized.
  If necessary, perform a reorganization of the number range. This can often be done by adjusting the number range intervals or extending the range.
  
  
  
  Extend the Number Range:
  
  If the current number range is too small, you can extend it by adding more numbers to the range.
  This can be done in the same SNUM transaction by editing the number range intervals.
  
  
  
  Check for Configuration Issues:
  
  Review the configuration settings for number ranges in the Asset Accounting module to ensure they are set up correctly.
  Ensure that the number range is not restricted by any other settings or configurations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed steps on managing number ranges and performing reorganizations.
