Issue in breakdown indicator of Notification

Hello Experts,

I have a requirement, where if I access Tcodes (IW21, IW22, IW31 or IW32) any of these Tcode
to go to the order header screen.

I need to check the breakdown indicator of the Notification. If the breakdown indicator is checked, then the PMActType field in the Order header
screen should be '020' for order type 'PM10'.

I have used the Export/Import parameter concept for validation but it is causing issues when handled in large cases.

Kindly suggest me suitable methods of validation to achieve the above requirement.
