Capacity check is not working while creation of Production order

Question

HI Gurus,
I want to restict the system that in case of insufficient capacity at the work centers, sysstem should not create the production order. For that i did the setting
1) Unchecked the tick for the Capacity check & enter the profile SAPSFCG013 in the OPJK for the business functions 1 & 2.& also make the setting for the Release order '3".
2) Maintain the same profile in the production profile & maintain that profile in the Mat Master
3) In the CR02, activate the tick for the finite scheduling & uncheck for the can used for several operations.
But i have creted the production orders & at the time of capacity check system is giving the message " Capacity avaiolable at all the work centers. But i check in the CM50, all the work centers are overloaded at the respective date.
But i can create & release the p[orduction order.
Requesting all to give your comments & solutions.
Regards
ACP

ACP,
....after confirming all the operations system is allowing me to save
When you confirm an order, you are by definition saying that the capacity existed for that order (you have just declared to the system that all operatons have been performed, and therefore all capacity was available).  I can't imagine why you would not wish to save that order, since you must somehow post the physical work that has already been done.  Capacity availability check is really only useful when the order to be checked has not yet been executed.
CM50 displays capacity requirements.  CM50 does not perform the same function as Capacity availability check.  To ensure that all of your orders fall within you capacity constraints, you must perform capacity levelling.  Capacity availability check does not work the same as a Material availability check - don't assume that what you know about a material ATP will be applicable for a capacity ATP.  Read the help on Capacity levelling.  It is not generally possible to stop a manually created production order from being saved, due to any capacity situation, without using an enhancement.

Naturally, you can use enhancements to have the system meet any business requirement that is not met with the standard Cap Availability check.
