Automatic clearing with tolerance for GL for difference in fraction

Hello,

I have configured automatic clearing with tolerance of 5 per for a GL account.

Made necessary configuration ob74,oba0 and assigning GRP to gl.

It works fine when difference is greater than 1 USD or 1 AED.

Automatic clearing is not working for small differences like 0.01 and 0.02.

I am trying to clear two documents in two different currencies through f13e with currency AED.

Please let me know y configuration is failing to clear documents for such small differences.

Regards,

Priti
