Clearing documents creates line items

Hi FI guys,

When I am clearing Vendor line items using F-44, a clearing document is getting genearted. Usually, such a document should not have any line items. But the system is posting a document WITH line items:

Vendor A/C Dr

Vendor A/C Cr

Can anyone please tell me why this happens and how I can stop these line items from getting generated?

Thanks for your efforts.
