ME_PROCESS_PO_CUST Plant and Cost Center Validation Isuue

Question

Hi Friends,
                  I have a requirement to validate ME21N PO creation with Account assignment 'K'. In our Business Process, we have 2 plants lets say 3000 and 5000. Plant 3000 is linked to Business Area say 4000 and Plant 5000 is linked to Business Area 9000. Now we have unique cost center assignment in both Business areas.
My requirement is when i enter wrong cost center then system has to validate it with plant and has to pop up error message in PO creation. With BADI ME_PROCESS_PO_CUST, i am able to populate the error message when i enter wrong cost center but i can save the PO which is wrong.
Please help me on this issue.
I have written in my logic in BADI ME_PROCESS_PO_CUST -> PROCESS_ACCOUNT.
Thanks,
-Ziad
