Defining "Open Item Management"
Use
If you set the "Open item management" indicator in the master record for an account, the line items in this account is marked as open or cleared.
The balance of an account with open item management is equal to the balance of the open items. General ledger accounts are kept with open item management if you need to check whether there is an offsetting posting for a given business transaction.
Recommendation
You should use open item management for bank clearing accounts, clearing accounts for goods receipt/invoice receipt, and salary clearing accounts.
Bank accounts, however, do not use open item management.
If you subsequently define open item management for a G/L account, this entry only applies to the items which are posted afterwards. At the date of the change, the account must display a zero balance.
Also, when canceling this indicator, the balance must be zero. You therefore have to clear the remaining open items before making the change in the master record.
