Status release error

Question

Dear all,
when i'm trying to release activity in the project, the following error triggers:
Order type PS05 plant ALSH: No checking rule maintained for operation
Message no. CO288
Diagnosis
To carry out a material availability check, the system needs a check rule.  No check rule has been maintained for order type PS05 and plant ALSH for this business transaction (for ex. "order creation" or "order release").
Procedure
Maintain the checking group for the corresponding plant, order type and key (business transaction).
Key 1: control for automatic checking on
order creation or manual checking for orders that have not been released.
Key 2: control for automatic check on order release or manual check for
partially released or released orders.
so, how can i Maintain the checking group for the corresponding plant, order type and key (business transaction). ?????????????/

Answer 1

Entries for checking control are missing. T Code OPJK, maintain the details for plant and order type.
