SAP Note 23575 - Lack of performance when creating production orders

Symptom:

If capacity planning is activated for a control-key, which is used in a production order, (transaction OP00, field V_T430-TERM ) then creating production orders is very slow. If this indicator is reset, then the order can be saved injust a few seconds.

Cause and prerequisites

The control-key in the operation requires capacity planning in the work center, however, the fields in the standard available capacity are not maintained.

Solution
Please check the capacity header in the scheduling screen in the work centers. If the fields in the standard available capacity are not maintained, the system will look at every day in the calendar and performance suffers as a result of this.
