Product Allocation Determination

  1. Upon entry of the sales order into the OLTP system, the product allocation procedure is read from the ATP product master record.
  2. If a sequence of product allocation procedures exists, the subsequent procedures are read from this product allocation sequence.
  3. There could be a number of steps for each product allocation procedure. Each step is associated with a product allocation group.
  4. In each product allocation group there may be multiple product allocation objects that cover a corresponding data area.
  5. For each product allocation object, there is a time series of planned product allocation quantities associated with a set of characteristics.
  6. The first procedure is determined from the ATP tab page in the product master, corresponding to the product of the sales order item. If the location-dependent product allocation procedure is missing, then the location-independent procedure is used.
  7. The first step in the procedure is examined. Based on the sales order date, a valid product allocation object and its associated characteristics/time series is examined, if and only if there is a matching characteristic with or without the wildcard character. If there are matching characteristics and remaining available quantities, a product allocation is made.
  8. If the first step fails, the second/next step is examined. Each step should be designed to check for product allocation objects with fewer or more general characteristics (Example: From customer/DC level in step 1 to DC level only).
