You can select all IDocs transferred to the ALE layer according to various criteria and control the data sent.

You can use this function to check whether the transactional RFC actually transferred data to the target system.

With this function module you can monitor the entries to check if there were any problems during the transmission of the IDocs to the logical system. You can check the results in two tables: IDOC_QUEUE and TRFC_QUEUE and determine which of these two tables should be returned. You can define the maximum number of entries per table to avoid receiving very large quantities of data at once. You can also limit the choice of IDocs for a logical system by setting date and time restrictions.

If an IDoc in the IDoc queue has one of the following statuses, the entries are transmitted to the external system. If it has any other status, a transactional RFC is sent. It is not enough to check only the IDoc Queue because although an IDoc may have been created correctly, a problem could have occurred during transmission. Transmission problems are checked in table TRFC Queue
