Capture and post in single transaction J1IEX

Hello

Business requirement is that:

Business do not want to give any excise related activity to stores persons. So i,e the reason they will do the GR with Ref to Purchase order with Option "NO excise entry" in MIGO.

Now they want to make the Capture and Post in single transaction through J1IEX. If we select J1IEX with ref to GR then system will generates the Internal number, but it will not update J_1IPART1 and J_1IPARt2.

How to Capture and post in single step?m means how to update J_1IPART1 and J_1IPART2
