• What is the cause and solution for SAP error message GK859 - External number assignment not allowed with automatic reversal ?

  The SAP error message GK859, which states "External number assignment not allowed with automatic reversal," typically occurs in the context of financial transactions, particularly when dealing with document postings that involve automatic reversals. This error indicates that the system is trying to assign an external number to a document that is set to be automatically reversed, which is not permitted.
  Cause:
  
  External Number Range: The document type you are using is configured to use an external number range, but the automatic reversal feature requires an internal number range.
  Configuration Settings: The configuration settings for the document type may not allow for automatic reversals when using external number assignments.
  Document Type Settings: The specific document type being used may not be set up correctly to handle automatic reversals.
  
  Solution:
  
  
  Change Number Range: If you need to use automatic reversals, consider changing the number range from external to internal for the relevant document type. This can be done in the configuration settings of the document type.
  
  Navigate to SPRO ? Financial Accounting ? Financial Accounting Global Settings ? Document ? Document Types ? Define Document Types.
  Select the document type in question and check the number range settings.
  
  
  
  Review Document Type Configuration: Ensure that the document type is configured correctly to allow for automatic reversals. You may need to consult with your SAP administrator or a functional consultant to verify the settings.
  
  
  Manual Reversal: If changing the number range is not feasible, consider performing a manual reversal instead of an automatic one. This would bypass the restriction imposed by the external number assignment.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific version of SAP you are using, as there may be additional considerations or updates that apply.
  
  
  Related Information:
