Satish,
CO09 displays the Availability situation. This display will work whether or not you are conducting ATP in ERP or in SCM.
However, first the material must be relevant for Availability checking. I suspect that your Material Master does not have an entry in the "Availability Check" field in the MRP3 tab of MM02. Place a valid entry there, and then CO09 should display something.
Best Regards,
