Active BADI Implementation not working now

Hi,

I have created a Implementaion for BADI ME_PROCESS_PO_CUST., and written my code. It was working fine.

Now, after a long gap when today I run the process the BADI ME_PROCESS_PO_CUST implementaion is not working.I have kept debug point in all methods for the implementation.But, still its not getting triggered.

Am in a fix. What possibly could be the problem?There is no multiple implementations for this BADI too..

Please help me.

Thanks,

Shivaaa........
