Hi Azam H,
Once you have executed any of the scenarios, it is possible that you might not see the messages, depends on if you have activated the log in EWM for required object or not.
But you can go to tcode /SCWM/GRPE (GR Preparation) to make sure if your PO is reached to EWM or not. Here you can enter your PO number and execute, it will show your PO if it has reached to EWM it does not matter which of the scenarios (pull or push) you have used.
