• What is the cause and solution for SAP error message WRF_MATERIAL081 - Conversion factors must be greater than 1 ?

  The SAP error message WRF_MATERIAL081 indicates that there is an issue with the conversion factors defined for a material in the system. Specifically, the error states that the conversion factors must be greater than 1. This typically occurs in the context of materials that have multiple units of measure (UoM) defined, and the conversion factors between these units are incorrectly set.
  Cause:
  
  
  Incorrect Conversion Factor: The conversion factor defined for a unit of measure is less than or equal to 1. For example, if you have a base unit of measure (e.g., "EA" for each) and a secondary unit of measure (e.g., "KG" for kilograms), the conversion factor should indicate how many base units are equivalent to one secondary unit. If this factor is set to 1 or less, it will trigger this error.
  
  
  Data Entry Error: During the creation or modification of material master data, an incorrect value may have been entered for the conversion factor.
  
  
  Configuration Issues: There may be issues in the configuration of units of measure in the system, leading to incorrect conversion factors being applied.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM02 for change).
  Navigate to the "Basic Data" or "Units of Measure" view.
  Review the conversion factors for the relevant units of measure.
  Ensure that all conversion factors are greater than 1 where applicable.
  
  
  
  Correct Conversion Factors:
  
  If you find any conversion factors that are less than or equal to 1, update them to appropriate values. For example, if 1 KG = 1000 G, the conversion factor from KG to G should be set to 1000.
  
  
  
  Validate UoM Configuration:
  
  Check the configuration of units of measure in the system (transaction code OMN1 for unit of measure settings).
  Ensure that the units of measure and their conversion factors are correctly defined in the system.
  
  
  
  Test Changes:
  
  After making the necessary changes, test the material to ensure that the error no longer occurs.

  Documentation: Refer to SAP Help documentation for detailed information on material master data and units of measure.
  User Roles: Ensure that you have the necessary authorizations to make changes to material master data and unit of measure settings.
  
  By following these steps, you should be able to resolve the WRF_MATERIAL081 error and ensure that your material master data is correctly configured.
