  The SAP error message CPCL_VERS156 indicates that a Material Bill of Materials (MBOM) for a unitized material does not have effectivity. This typically occurs in the context of production planning and control, where the system expects a valid effectivity date or range for the BOM to be used in production.
  Cause:
  
  Missing Effectivity Dates: The MBOM for the specified material does not have any effectivity dates defined. Effectivity dates are crucial for determining when a particular BOM is valid for use.
  Incorrect Configuration: The configuration of the material or the BOM may not have been set up correctly, leading to the absence of effectivity.
  Data Inconsistency: There may be inconsistencies in the data related to the material or BOM, such as missing entries or incorrect settings.
  
  Solution:
  
  
  Define Effectivity Dates:
  
  Go to the BOM maintenance transaction (e.g., CS02) and check the BOM for the specified material.
  Ensure that effectivity dates are defined. You can set a start date and an end date for the BOM to specify when it is valid.
  
  
  
  Check Material Master:
  
  Verify the material master data for the unitized material. Ensure that it is correctly configured and that all necessary fields are filled out.
  
  
  
  Review BOM Status:

  Consult Documentation:
  
  Review SAP documentation or help resources for specific instructions on how to set up effectivity for MBOMs.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration by attempting to use the BOM in a production order or related transaction to ensure that the error no longer occurs.
