• What is the cause and solution for SAP error message CPCL_VERS155 - MBOM without effectivity for unitized material cannot be assigned ?

  The SAP error message CPCL_VERS155 indicates that there is an issue with the assignment of a Multi-Level Bill of Materials (MBOM) to a unitized material that does not have an effectivity date defined. This error typically arises in the context of production planning and material management within SAP.
  Cause:
  
  Missing Effectivity Dates: The unitized material (often a finished product or assembly) does not have an effectivity date assigned in the system. Effectivity dates are crucial for determining when a particular BOM is valid for use in production.
  Incorrect BOM Configuration: The BOM may not be properly configured or may not be linked to the correct material.
  Material Master Settings: The material master record for the unitized material may not be set up correctly, particularly in relation to the BOM and effectivity settings.
  
  Solution:
  
  
  Assign Effectivity Dates:

  Use transaction codes like CS03 (Display BOM) to review the BOM details.
  
  
  
  Review Material Master:
  
  Check the material master record for the unitized material using transaction code MM03. Ensure that the relevant views (like Basic Data, MRP, and Work Scheduling) are correctly filled out.
  Make sure that the material type and other settings are appropriate for the type of material you are working with.

  Review SAP documentation or help files related to BOM management and effectivity settings for further guidance.
