1. Go to the Manage Production Orders app.
2. Select an order.
3. Click "Check availability" button
4. Error message CO462 "Order type xxxx, plant xxxx: Checking rule missing" occurs.

Cause 1：
In configuration activity 102447 - Define Checking Control, for the order type and plant combination, the material availability check is set as "No Check".
Note : 'No check' means no automatic material availability check is to be executed for the specified business transaction (order creation or order release). The option of calling up a material availability check manually and also of executing a collective availability check is not affected by setting this indicator.

Cause 2：
There is no entry for the plant and order type combination in configuration activity 102447 - Define Checking Control.
Or, the entry exists, but the checking rule for Material availability is not maintained in it. 

For cause 1:
Tick off the "No check" indicator and maintain the checking rule.

For cause 2:
Maintain an entry for the plant and order type combination in configuration activity 102447 - Define Checking Control, and select the correct checking rule in the "checking rule" field under "Material availability" section.
