2 users open same UDO screen and update/add records same time.
Also "Start Transaction" starts to update/add linked another tables when user update/add UDO record(Parent and child UDO) from UDO screen.
Problem is second user's screen is hang with locking when 2 users records are on same page.
Does SAP B1 use page level locking or record level locking?
If SAP B1 uses page level locking, how to solve this locking problem?
