The system takes into account different product allocation control phases during the overall constraint period.
You can assign several product allocation objects to the product allocation procedure. A validity period exists for each object. The system determines the relevant object on the basis of the check date. The system then uses this object to determine the corresponding planning hierarchy that contains the product allocations.
Objects are always valid from the end date of the last object. To switch off the product allocation for a certain period, you have to define a dummy object and set it to inactive.
The system allows three types of check dates:
Material availability date
Planned goods issue date
You can maintain time-dependent conversion factors for your product allocation objects in Customizing.
