• What is the cause and solution for SAP error message VO723 - Unexpected return code UNIT_CONVERSION_SIMPLE: & ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  VO723 Unexpected return code UNIT_CONVERSION_SIMPLE: &
  
  Cause:
  This error typically occurs during unit of measure (UoM) conversions in SAP, especially when the system tries to convert quantities between different units but encounters an unexpected or undefined return code from the unit conversion function/module.
  
  The message VO723 is related to the unit conversion logic in SAP SD (Sales and Distribution) or MM (Materials Management) modules.
  The UNIT_CONVERSION_SIMPLE function/module is called internally to convert quantities from one unit to another.
  The unexpected return code indicates that the conversion function returned a code that the calling program did not anticipate, which usually means:
  
  The unit conversion factor is missing or incorrect.
  The units involved are incompatible or not maintained properly.
  There is a customization or master data inconsistency.
  A bug or inconsistency in the conversion logic or user exit/enhancement.
  
  
  
  
  Solution:
  
  
  Check Unit of Measure Master Data:
  
  Go to transaction CUNI (Units of Measure) or CUNI_MAINTAIN.
  Verify that the units involved in the conversion exist and are correctly defined.
  Check if the conversion factors between the units are maintained properly.
  Ensure that the units are compatible for conversion (e.g., weight to weight, length to length).
  
  
  
  Check Material Master Data:
  
  Use transaction MM03 to check the material's base unit of measure and alternative units.
  Verify that the units used in the sales order or purchase order are consistent with the material master.
  
  
  
  Review Custom Code or User Exits:
  
  If there are any user exits, BADIs, or enhancements related to unit conversion, review them for possible errors or unexpected return codes.
  Debug the process to see where the unexpected return code is generated.
  
  
  
  Check SAP Notes:
  
  Search for SAP Notes related to message VO723 or unit conversion issues.
  Apply any relevant patches or corrections suggested by SAP.
  
  
  
  Debugging:
  
  If you have developer access, debug the program where the error occurs.
  Check the return code from the function/module UNIT_CONVERSION_SIMPLE.
  Identify why the return code is unexpected (e.g., missing conversion factor, wrong input parameters).
