IDoc communication is predicated on transactional Remote call (tRFC).
You can optimize the performance of ALE processing by using the subsequent settings and procedures.
Suppressing Background Processing
If tRFC errors occurs in the standard SAP system, , a background job is generated to re-establish the connection. In certain circumstances this might end in an outsized number of background jobs being started that completely block backgrounding .
Note:
Use program RSARFCEX to restart tRFC to cancel a background job if tRFC errors occur .
Select a connection to change in ALE Customizing (transaction SALE),
Communication
Create RFC Connections (SM59)
Choose Destination ® tRFC Options and select the option Suppress Background Job at Comm. Error.
Setting Dispatch Status to OK
When an IDoc is passed to the communication layer, it's assigned a globally unique transaction identifier (TID). If the IDoc has been successfully dispatched, this information isn't automatically passed to the ALE communication layer. So that ALE processing sets the IDoc status to Dispatch OK, you ought to compare the TID numbers within the communication layer and therefore the ALE layer.
The SAP program RBDMOIND checks that the IDocs passed to the tRFC have already been sent to the receiving SAP system. If they need been sent, the IDoc status is modified to "12" - Dispatch OK
Note:
To set the IDoc dispatch status, run the program RBDOIND after the IDocs are passed to the communication layer.
Checking the tRFC Status
Use
Transactional RFC calls which transfer IDocs use the function module IDOC_INBOUND_ASYNCHRONOUS at reception (before release 4.0: INBOUND_IDOC_PROCESS).
If an IDoc in the sending system has been passed to tRFC (IDoc status "03"), but has not yet been input in the receiving system, this means that the tRFC call has not yet been executed.
Activities
To check the status of the tRFC calls, select Tools -> IDoc Interface/ALE -> Administration -> Monitoring -> Troubleshooting -> RFC Queue (SM58) and setout any additional selection criteria.
The program RSARFCEX restarts unsuccessful tRFC calls.
Note:
You cannot choose the choice is being executed in backgrounding .
