This error typically arises when you are trying to perform operations related to production, such as creating a production order or running a material requirement planning (MRP) process, and the system cannot find a valid BOM for the specified material on the date in question.
  Cause:

  Solution:
  
  Check BOM Validity: Verify the validity dates of the BOM for the material in question. You can do this by navigating to the BOM in the SAP system (Transaction CS03) and checking the validity period.
  Create or Update BOM: If the BOM does not exist or is not valid for the required date, you may need to create a new BOM or update the existing one to include the necessary validity dates.
  Check Plant Assignment: Ensure that the BOM is assigned to the correct plant. If it is not, you may need to create a plant-specific BOM.
