 Date Determination when an Order is Created Locate this document in the navigation structure

Use

The determination of dates depends on the order creation type. A production order is created by

  • Converting a planned order into a production order

  • Creating a production order manually

Features

Converting a Planned Order into a Production Order

If material requirements planning has already created a planned order for producing the material, the basic dates are copied from the planned order and the order start and finish dates are determined in a new scheduling run. If necessary, reduction measures are carried out.

Creating a Production Order Manually

If no planned order exists and you create the production order manually, the scheduling type determines which basic dates you have to enter.

If you enter both basic dates, the system tries to adhere to these dates when carrying out forwards or backwards scheduling. If necessary, the system also carries out reduction measures.

The following tables show which dates you have to enter and which dates are calculated via scheduling.
