The availability check processes requirements according to a strict FIFO principle. The time at which the availability check is called in the document is decisive (that is, the entry date during the order creation or the date on which a document is changed).

With the sort criteria for rescheduling you can influence to a certain degree the sequence in which the requirements records are transferred to the availability check (for example, by sorting the requirements according to requested delivery date).

The sorting of requirements during the allocation depends on your individual settings, however. Using special sorting rules, you can sort requirements so that the original sequence in which the orders were placed is overridden (for example, by sorting according to customer number, document category, and so on).

Please note the following before rescheduling:

• The criteria according to which the requirements are sorted during the allocation
• Whether these sort criteria can also be used during rescheduling
• The sequence in which the allocation and rescheduling should be executed for the best possible result

You can control the requirements sorting during the allocation according to various criteria / in combination with various criteria so that your individual needs are fully met.

In rescheduling you can only choose from the criteria entry date, entry time, delivery priority, and requested delivery date.
