  Error Message
  WSFP_MESSAGE021: Error converting unit of measure &1
  
  &1 is a placeholder for the unit of measure (UoM) that caused the error.
  
  
  Cause
  This error occurs when SAP Workflow Processing Framework (WFP) tries to convert a quantity from one unit of measure to another, but the conversion fails. The reasons can include:
  
  
  Missing or Incorrect Unit of Measure Conversion Factor:
  
  The system does not have a defined conversion factor between the source and target units of measure.
  For example, if you try to convert from "KG" to "LBS" but no conversion factor exists in the system.
  
  
  
  Invalid or Non-Standard Unit of Measure:
  
  The unit of measure provided (&1) is not recognized or is invalid in the system.
  It might be a typo or a unit that is not maintained in the unit of measure table.
  
  
  
  Data Inconsistency:
  
  The unit of measure is not maintained properly in the material master or related configuration.
  The unit might be missing in the relevant customizing tables.
  
  
  
  Incorrect Usage in Workflow or Program:
  
  The workflow or custom program is passing an incorrect or unsupported unit of measure.
  
  
  
  
  Solution
  To resolve the error, follow these steps:
  
  
  Check Unit of Measure in Material Master:
  
  Go to transaction MM03 and verify the units of measure maintained for the material.
  Ensure the unit &1 is valid and maintained.
  
  
  
  Maintain Unit of Measure Conversion Factors:
  
  Use transaction CUNI (Units of Measure) to check if the unit &1 exists.
  Use transaction CUNI or SPRO path:
  
  Logistics ? General ? Units of Measure ? Define Units of Measure
  Logistics ? General ? Units of Measure ? Define Unit of Measure Groups
  Logistics ? General ? Units of Measure ? Define Conversion Factors
  
  
  Ensure that conversion factors between the relevant units are maintained correctly.
  
  
  
  Check Workflow or Program Logic:
  
  If this error occurs in a workflow, check the workflow container or the program logic that handles unit conversions.
  Make sure the unit of measure passed is valid and conversion is possible.
  
  
  
  Check for Customizing or Master Data Issues:
  
  Verify if any custom units of measure are used and if they are properly configured.
  Check if the unit of measure is consistent across all relevant master data and customizing.
  
  
  
  Debugging:
  
  If the error persists, debug the workflow or program to identify where the conversion fails.
  Look for the function module or method that performs the conversion (e.g., CONVERSION_EXIT_* or standard SAP conversion functions).

  Summary
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Missing or incorrect unit of measure conversion factor; invalid or unmaintained UoM.
  
  
  Solution
  Maintain correct UoM and conversion factors in CUNI; verify material master and workflow logic.
