When an IDoc is transferred to the communication layer, a transactional RFC (tRFC) forwards it to an external system. The ALE layer transfers the IDoc.
The ALE layer processes the outbound IDoc and controls its dispatch. Depending on the partner profile settings in Customizing for ALE, IDocs can be transferred in the following ways:
· IDocs assigned to the same partner and message type are collected and the RSEOUT00 program later forwards them to the communication layer.
To do this, in ALE Customizing (Transaction SALE) choose:
Set-Up System Monitoring
Schedule Collected IDoc Transmission (SM36)
You can also send the collected IDocs to the communication level manually, in the ALE Administration under Monitoring ®IDoc Display ® Status Monitor.
· The IDoc is forwarded to the communication layer immediately.
You should use the outbound processing mode Collect IDocs, especially if you are distributing master data. System performance is better.
You can also Process IDocs in Packets in the "collect" processing mode.
To go to the ALE administration functions, from the SAP menu choose
Implement and Configure Business Processes
Generate Partner Profile
Under outbound parameters choose the output mode Collect IDocs and transfer.
