• What is the cause and solution for SAP error message FKKMA021 - Caution: Number range &1 (object &2) has reached upper limit ?

  The SAP error message FKKMA021 indicates that a number range has reached its upper limit for a specific object. This typically occurs in the context of Financial Accounting (FI) and Contract Accounts Receivable and Payable (FI-CA) modules, where number ranges are used to generate unique identifiers for various documents, such as invoices, payments, or contracts.
  Cause:
  The error is triggered when the system attempts to generate a new document number, but the defined number range for that object has exhausted its available numbers. This can happen if:
  
  The number range is not sufficiently large to accommodate the volume of documents being processed.
  The number range has not been properly extended or adjusted to allow for more numbers.
  The number range has been incorrectly configured or is set to a fixed limit.
  
  Solution:
  To resolve the FKKMA021 error, you can take the following steps:
  
  
  Check the Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Enter the object name (e.g., FKKMA for contract accounts) and check the current number range settings.
  Review the current upper limit and the number of used numbers.
  
  
  
  Extend the Number Range:
  
  If the number range is indeed exhausted, you will need to extend it.
  In transaction code SNRO, select the number range object and adjust the upper limit to a higher value.
  Ensure that the new range does not conflict with existing ranges.
  
  
  
  Create a New Number Range:
  
  If extending the existing number range is not feasible, consider creating a new number range.
  This can be done in the same SNRO transaction by defining a new range and assigning it to the relevant object.
  
  
  
  Check Authorizations:
  
  Ensure that you have the necessary authorizations to make changes to number ranges. You may need to involve a system administrator or someone with the appropriate permissions.
  
  
  
  Test the Changes:
  
  After making changes, test the system to ensure that new document numbers can be generated without errors.

  Best Practices:
  
  Regularly monitor the usage of number ranges to prevent reaching the upper limit.
  Plan for number range adjustments during periods of expected high volume, such as month-end or year-end processing.
  
  
  
  By following these steps, you should be able to resolve the FKKMA021 error and ensure that your SAP system can continue to generate document numbers without interruption.
