Tolerance for Invoices

Dear All,

Is there a way to set Tolerance as per the below scenario.

10% is limit for tolerance btw the IR and GR. However subject to $1 million as upper limit i.e., for example:

GR 20 million

IR 21.5 million (10% will be 2 million) , however here variance is 1.5 million which exceeds amount limit of 1 million

So tolerance exceeding and should not proceed further.

Please guide us how to acheive this in SAP.

regards

Diwakar
