GR IR Auto Clearing - TCode F.13

Dear Friends,

I am clearing the GR/IR using Tcode:F.13 and prerequisites are already done:

Additional Rules for Automatic Clearing :

1001    S    1109001300    1109001320    ZUONR    WRBTR

For above GL Account 1109001320 is still not clearing the line items which Assignment and Amount is same.

There is not mentioned Business Area in the configuration, and as per the data it comes some time with different business area too but both type of data wont get clear in the system.

Can any one help to understand why it is not clearing the line items.

Regards,

Rajesh K.
