Smart SAP Assistant

• What is the cause and solution for SAP error message O9084 - UoM group of component &1 <> &2 of main material &3 item: &4 ?

  The SAP error message O9084 indicates a mismatch in the Unit of Measure (UoM) group between a component and the main material in a bill of materials (BOM) or a production order. This error typically arises when the UoM group assigned to a component does not match the UoM group of the main material.
  Cause:
  
  UoM Group Mismatch: The component's UoM group is different from that of the main material. Each material in SAP is assigned a UoM group that defines how quantities are measured and converted.
  Incorrect BOM Configuration: The BOM may have been configured incorrectly, leading to the inclusion of components with incompatible UoM groups.
  Material Master Data Issues: The material master data for either the main material or the component may not be set up correctly, leading to discrepancies in UoM groups.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master records for both the main material and the component.
  Verify the UoM group assigned to each material. You can do this by using transaction code MM03 to display the material master and checking the "Basic Data" or "Purchasing" views.
  
  
  
  Update UoM Group:
  
  If you find that the UoM groups are indeed different, you may need to update the UoM group of the component or the main material to ensure they match. This can be done using transaction code MM02 to change the material master data.
  
  
  
  Review BOM Configuration:
  
  Check the BOM configuration using transaction code CS03 to ensure that all components are correctly defined and that their UoM groups are compatible with the main material.
  
  
  
  Recreate BOM:
  
  If the BOM is significantly misconfigured, it may be easier to recreate the BOM with the correct components and UoM groups.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for any specific configurations or settings that may be affecting UoM groups.

  MM02: Change Material Master
  CS03: Display BOM
  CS01: Create BOM
  CS02: Change BOM
  
  
  
  UoM Groups: UoM groups can be defined in the material master and can include various units like pieces, kilograms, liters, etc. Ensure that the UoM groups are set up correctly in the system.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to UoM groups and BOM configurations.
  
  
  By following these steps, you should be able to resolve the O9084 error and ensure that the UoM groups for your materials are correctly aligned.
