Wait Step is not working in BPM, any extra settings required?

Dear Friends,

I am working on BPM scenario first time.

I am sending the Idoc from one ECC system to ohter ECC system using XI.

but in receiver side it has to updated after 60 minutes, for this 60 minutes requirment I am using Wait condition in BPM, but it's not waiting 60 minutes.

the Idoc is receiving reciever side whenever sender is sending the Idoc.

the Idoc is not going through BPM,it's going directly. In this case can I do some extra settings?

In BPM Receiver-wait-send step types are used.

Please help me in this issue.

Regards,

Shalini Shah.
