Wrong entry with payment difference

Hi Experts,

I am facing the wrong entry when clearing the vendor open item using F-53 but i have maintained the GL account in OBXL as well as the tolerance value is 10.

Entry is:

Vendor account             Dr. 10000 

Payment Difference a/c Cr. 9

Vendor account             Dr. 9

Bank clearing account   Cr.10000

Could you please let me know the right entry with payment difference for vendor clearing and missed configuration steps.

Thanks and Regards,

Babu
