ESS MSS Workflow with SAP ABAP Dynpro application

Hello Experts,

I have the requirement where we need to 2 level approval for ESS MSS..

First when user click on the particular tab and change button , it will show the

one screen, where we need to enter data and save.

Once save same screen we have to create in MSS with APPROVE and REJECT Button?

My question is how to create the Screen in MSS and how to link the ESS in MSS
