• What is the cause and solution for SAP error message AC194 - Number range &1 in co.code &2 for doc.type &3 must be defined as external ?

  The SAP error message AC194 indicates that there is an issue with the number range configuration for asset accounting in a specific company code and document type. This error typically arises when the system expects the number range to be defined as "external," but it is not set up that way.
  Cause:
  
  Number Range Configuration: The number range for asset documents in the specified company code and document type is not defined as external. In SAP, external number ranges allow users to manually enter document numbers, while internal number ranges are automatically generated by the system.
  Document Type Settings: The document type associated with the asset transaction may not be configured correctly to use an external number range.
  Missing Configuration: The necessary configuration for the number range may not have been completed in the system.
  
  Solution:
  To resolve the AC194 error, follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code OAVN (for number range intervals for asset accounting).
  Check the number range intervals for the relevant company code and document type.
  Ensure that the number range is set to "external" for the specified document type.
  
  
  
  Adjust Document Type Settings:
  
  Go to the transaction code OBA7 (for document types).
  Select the document type associated with the asset accounting transaction.
  Verify that the document type is configured to use an external number range.
  
  
  
  Create or Modify Number Range:
  
  If the number range does not exist or is incorrectly configured, you may need to create a new external number range or modify the existing one.
  Ensure that the number range is properly assigned to the relevant company code and document type.
  
  
  
  Testing:
  
  After making the necessary changes, test the transaction again to ensure that the error is resolved.
