Availability Check Against Product Allocation During Order Entry SD

The planning hierarchies for product allocations are created in logistics controlling. If the correct settings have been made in Customiuing, the system carries out an availability check against the ATP quantity in SD during order entry. If the availability check determines that the ATP quantity can fully or partially cover the order requirement, then a confirmed quantity is determined as the result of the check. The confirmed quantity is the basis for the availability check against product allocation, which is carried out along with the ATP check.

The confirmed quantity from the ATP check is checked against the relevant product allocation. This ensures that the product allocation for this period is not exceeded. Required quantities that cannot be confirmed, because the product allocation for that period is used up, are postponed until the next period.

The result of the product allocation check can change confirmed quantities that have already been determined. In this case you receive a message before branching to the availability control screen.

For example, even though the material for an order for 100 pieces may be available in full for the required date according to the ATP check, it is only partially confirmed because the product allocation for that customer only had a value of 80 pieces remaining at the time of order entry. The confirmed quantity for the required quantity and an alternative delivery date is displayed on the control screen.

Unlike the ATP check, the check date for the availability check against product allocations is the planned delivery date for the customer and not the material availability date.

The actual order quantities are updated in the planning hierarchy of the LIS. Comprehensive reporting tools and an early warning system in the LIS that has to be set in Customizing monitor the status of the product allocation period and report critical situations immediately.

Product allocation uses a blocking mechanism similar to quantity block in the ATP check: The check hierarchy of the corresponding product allocation object is only blocked exclusively during the check itself. Afterwards, the same object can also be used by other processes without the current procedure having been saved. The product allocation quantity used is, however, seen in all subsequent processes (via this blocking mechanism) to prevent over-confirmation.
