• What is the cause and solution for SAP error message 69390 - Customizing error: Check digit calculation may only occur once per number ?

  The SAP error message 69390, which states "Customizing error: Check digit calculation may only occur once per number," typically arises in the context of number ranges or number assignment in SAP systems. This error indicates that there is an issue with the way check digits are being calculated for a specific number or number range.
  Cause:
  
  
  Duplicate Check Digit Calculation: The error occurs when the system attempts to calculate a check digit for a number that has already had a check digit calculated. This can happen if the configuration for number ranges or check digit settings is incorrect or if there is an attempt to reprocess a number that has already been assigned a check digit.
  
  
  Configuration Issues: The customizing settings for the number range or check digit calculation may not be set up correctly, leading to conflicts when the system tries to generate or validate numbers.
  
  
  Custom Code: If there is custom code or enhancements that manipulate number generation or check digit calculations, they may inadvertently trigger this error.
  
  
  Solution:
  
  
  Review Number Range Configuration: Check the configuration of the number ranges in the relevant transaction (e.g., SNRO for number ranges). Ensure that the settings for check digit calculation are correctly defined and that the number ranges are not overlapping.
  
  
  Check Customizing Settings: Go to the customizing settings for the specific application area (e.g., Sales and Distribution, Materials Management) and verify that the check digit calculation is set up correctly. Ensure that it is only enabled for the intended number ranges.
  
  
  Debugging: If the issue persists, consider debugging the process to identify where the check digit calculation is being triggered multiple times. This may involve looking at custom code or enhancements that could be affecting the standard behavior.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific module you are working with. There may be specific guidelines or known issues that can provide further insight.
  
  
  SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They may have additional insights or patches that can help resolve the error.
