Notification required if 70 % of MIRO is done for a PO

Dear Experts,

I have one scenario which i like to share and want your valuable input on this.

In business scenario as a PO created and MIGO and MIRO done for that PO. So what we required that is if during MIRO process the invoice amount in reference of PO reaches to 70 % of PO amount then it should generate some kind of notification, reminder or message(POPUP).

So is there any configuration setting available through which it can achieved in SAP or i have to look for ABAPER's help.

Please suggest some FM if it can help me in some way.

Regards

Arun
