Hi
check the below link
For a list of IDoc Interfaces that support IDoc views, see SAPNet Note 185445.
Prerequisites
You must have IDoc development authorization (authorization object S_IDOCDEFT, for example in the role SAP_BC_SRV_EDI_DEVELOPER) before you can define a view.
check by transaction /nSU53
In IDOC_OUTPUT_ORDERS function module that creates the outbound ORDERS05 IDoc.
--> EXIT_SAPLEINM_002 will be called repeatedly for each IDoc segment while the IDoc is still building
--> EXIT_SAPLEINM_011 will be called once for the whole IDoc, once SAP finished building it
So yes, you can use any of these user exits to manipulate the output IDoc.
Also, the break point won't get triggered when output type is set to trigger immediately (dispatch time 4) when you issue the output from ME22N / ME23N, because the IDoc will be triggered asynchronously in this mode by the system and not in your session, so your session break points are ineffective.
What you need to do is go into the ME22N output page (Click Messages on ME22N screen, select the condition type in yellow color (not yet processed), click on "Further data"and set "Dispatch time" to 1 (Send with periodically schedule job). After doing this issue the output (by saving the PO etc). This will mean that the output IDoc is not triggered immediately.
Now put the break point in the suggested user exit.
Come to SE38 and execute RSNAST00 program, give "Output application" as "EF", object key as your PO number (format it with leading zeros for full 10 digits) and enter your output type. Run it and then you will see that your break point is hit.
