· As a rule, audit reporting is usually more efficient than IDoc tracing because the confirmations from the receiving system are already in the outbound system.
· The audit database is only updated periodically. Although this time interval is variable, newly created IDocs only appear in the audit report after a time delay.
· With system-wide IDoc tracing information is obtained from the receiving system synchronously.
· Unlike ALE audit, you can only use IDoc tracing with logical systems and not with EDI communication partners such as customers and vendors.
With ALE audit you can easily monitor the IDoc transfer from the sending system provided that time is not an essential criterion for the transfer.
