You can also check the document for completeness (optional). For example, the system checks whether the document balance is zero, and whether entries have been made in all required entry fields (such as posting key and account number).

This is sufficient to enable you to assign authorizations which differentiate between clerks who only have parking authorization and those who can post documents too.

No tolerance checks are carried out.
The system then carries out checks for erroneous entries. You are not, for example, permitted to enter an undefined business area.

Batch input is possible for parked documents.
