• What is the cause and solution for SAP error message FKYCHK020 - Current number &1 greater than/equal to interval end &2 ?

  The SAP error message FKYCHK020 indicates that there is an issue with the number range assignment in the context of financial accounting, specifically related to document numbers or other numeric identifiers. The message states that the "Current number &1 is greater than/equal to interval end &2," which means that the system is trying to assign a number that exceeds the defined range for that number series.
  Cause:
  
  Number Range Exhaustion: The current number being assigned (represented by &1) has reached or exceeded the maximum limit defined in the number range interval (represented by &2).
  Configuration Issues: The number range intervals may not be properly configured, or the intervals may not have been extended to accommodate the volume of transactions.
  Incorrect Number Range Assignment: The document type or transaction may be incorrectly assigned to a number range that is too small.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object.
  Ensure that the number range intervals are correctly defined and that the upper limit is sufficient for your business needs.
  
  
  
  Extend Number Range:
  
  If the current number range is exhausted, you may need to extend the number range. This can be done in the transaction code OBA7 (for financial accounting) or OINT (for other modules).
  Create a new interval or extend the existing interval to accommodate more numbers.
  
  
  
  Check Document Type Assignment:
  
  Ensure that the document type is correctly assigned to the appropriate number range. You can check this in the configuration settings for financial accounting.
  
  
  
  Reset Number Range:
  
  If necessary, you can reset the number range to a lower value, but this should be done with caution and typically only in a development or test environment.
