PO Strtergy Release Workflow

Dear All,

I have a workflow whose sceanario is like this.

In a plant there are say 2 levels L1 and L2.

Now when the PO Strtegy is release a mail should shoot from L1 to L2.

But currently,the moment a PO is created a mail is shooted from L1 to L2.

I am using Object Type BUS2012 and the event RELEASESTEPCREATED

Kindly guide me on this.Is any other information required?
