• What is the cause and solution for SAP error message AM156 - Address number in critical number range; reorganization required ?

  The SAP error message AM156 indicates that the address number you are trying to use is in a critical number range, which means that the system has reached a limit for the address numbers in that range. This typically occurs in the context of Asset Accounting (FI-AA) when the system is unable to assign a new address number because it has exhausted the available numbers in the defined range.
  Cause:
  
  Exhausted Number Range: The address number range has been fully utilized, and no more numbers are available for assignment.
  Critical Number Range: The number range is defined as critical, meaning it is close to its limit and requires reorganization to free up space or extend the range.
  
  Solution:
  To resolve the AM156 error, you can take the following steps:
  
  
  Reorganize the Number Range:
  
  Use transaction code OAAR (or navigate through the menu: Accounting > Asset Accounting > Periodic Processing > Number Range Management > Reorganize Number Ranges).
  Execute the reorganization process to free up address numbers that are no longer in use.
  
  
  
  Extend the Number Range:
  
  If the number range is indeed exhausted, you may need to extend it. This can be done in the configuration settings.
  Use transaction code OANR to access the number range settings for address numbers.
  Adjust the number range to allow for more addresses to be created.
  
  
  
  Check for Inactive Addresses:
  
  Review the existing address numbers to identify any that are inactive or no longer needed. You can delete or archive these addresses to free up space.
  
  
  
  Consult Documentation:
