Dear Nag,
Explian to you with a example:
Two document were posted with below:
Document NO 1: 40 expense 1000 / 31 vendor 1000
============
Document NO 2: 21 vendor 1000/ 50 expense 1000
===============
then both two line items with posting key 31 and 21 are with same amount in debit and credit side,
so the balance for this account is Zero, then both two line items could be cleared in F-44.
IN Summrize, F-44 is for clearing vendor Open line items if the balance in these line items are zero.
Hope above infor.could help you to understand this function clearly.
With Best Regards,
Gladys xing
