OBA1 GL not getting picked.

Hi SAP Experts,

I have done the configuration in OBA1 where in i have assigned GL provided by client for Exchage Rate Gain & Loss. I have assinged GL in all the transactions.

But when i do the Customer Inv with exch rate from USD to INR (45.00) on 5 Nov 2011, but now when i do the Customer payment F-28 the exch rate from USD to INR (47.00) on 11 Nov 2011.

Since there is diff in exchange rate my GL in OBA1 are not getting picked in the above scenario. Also in OBA1 the GL assigned are not recon GL they are normal GL created for exchage rate Gain & loss

Any idea why this is happening ??

Regards.
