  The SAP error message VT163, which states "Number range & not defined for internal number assignment," typically occurs when the system attempts to generate a document number using an internal number range that has not been properly configured. This can happen in various modules, such as Sales and Distribution (SD) or Materials Management (MM), where internal number assignment is required.
  Cause:
  
  Missing Number Range Definition: The number range for the specific document type or transaction has not been defined in the system.

  Number Range Status: The number range may be set to "not active" or may have reached its limit.

  Assign Number Range to Document Type:
  
  Use transaction code VOTXN (for SD) or OMH1 (for MM) to assign the number range to the relevant document type.
  Ensure that the document type is linked to the correct number range.
  
  
  
  Check User Authorizations:
