BSEG CREATE event is not triggered using tcode FB60

Hi SAP gurus,

I have requirement to trigger release for payment workflow. I have configured workflow variant, assign it to company code, release group, release path, assign workflow variant and doc type to release path,assign workflow variant, release path,amount to workflow,define users with authorization to release payments.

But when I tried to create invoice using FB60, the event CREATED of business object BSEG is not triggered (this event thereafter will trigger WS00400012 for release for payment).

Please help me on this.

Thank you very much.
