Implementation Options

For materials that are planned according to the MRP and forecast-based planning procedures, the requirement dates in the future are known. Scheduling is always backward. The system automatically switches to forward scheduling only if the start date lies in the past.

Process Flow

  1. The system calculates the goods receipt processing time backwards using the requirements date and thus determines the order finish date.
  2. The system calculates the in-house production time backwards using the order finish date and thus determines the order start date.
  3. The system calculates the opening period backwards using the order finish date and thus determines the order opening date.
