• What is the cause and solution for SAP error message CM_EXPERT328 - The value assignment type assigned to the fact &1 has multiple values ?

  The SAP error message CM_EXPERT328 indicates that there is an issue with the value assignment type assigned to a fact in the system.

  Review Value Assignment Type: Check the configuration of the value assignment type in the system. Ensure that it is set up correctly to handle the expected number of values.
  Check Assigned Values: Go to the relevant object (e.g., material, classification) and review the assigned values for the value assignment type. Remove any duplicate or unnecessary values to ensure that only one value is assigned.
  Data Validation: Implement data validation checks to prevent users from entering multiple values in fields that are supposed to accept only one.
