Determining the Valid BOM 

Process Flow

  1. The system checks which BOM usage in the plant has the highest priority (see BOM Usage).
  2. For this usage, the system then checks whether there is a valid BOM for the explosion date (see Period/Area of Validity of BOMs). The explosion date is the planned start date of the planned order.
  3. If, for a particular production unit, you want to ensure that the total BOM structure is always exploded using the same explosion date and have assigned a BOM explosion number and fixed key date to the sales order, the planned independent requirement, or the planned order, the system chooses the BOM that is valid for this date (see BOM Explosion Number (Fixed Key Date)).
  4. The system checks, whether the chosen BOM has the status active for MRP (see BOM Status).
  5. If a multiple BOM exists, the system checks which alternative BOM corresponds to the preconditions of the alternative selection (see Multiple BOMs).
