Mapping Error - Dump source message to file adapter comm channel

Question

Hi
Does anyone know of a way to dump the source message to a file adapter comm channel if - and only if - the message fails during mapping. For example, we receive a message from a trading partner that lacks an element that is mandatory during the mapping. When the mapping fails, the source message is sent - as is - to a file adapter comm channel.
I don't need anything more than the source message i.e. no need for any errors etc... to be included.
The kicker.. I would like to do this without using BPM if at all possible.
Any ideas greatly appreciated. Thx, Duncan

Hey Ram,
Go to Integration Directory and open the Receiver Determination for your scenario.
Check the configured receiver services. They are in a table-like area in the middle of the screen.
In this table of configured receiver services for that particular Sender Service/Interface, you should have the system that normally receives that message (your ERP or any other application system) and the service that contains the receiver file comm channel that will receive the message in case of error.
Check help.sap.com for help on condition editor on receiver determinations.
Now, the issue. You can only check whether a field exists, you can't check whether it doesn't exist (There's only a "EXIST" operator, and no negative operator). Thus, you can only do the following: always send messages to File, but you can avoid messages that dont have field from being sent to App System. Yeah, that sucks...
But don't fear, young padawan! There is a possible workaround. =D
In your message mapping, do the following for that particular field:
If field exists (check with Exist and IF standard functions) just bypass the field. Else, map the field with an impossible value (like string "$CREATED$"). Then, in your receiver determination, you will do the following conditions:
for App System: If field =/= $CREATED$
for File Receiver: If field = $CREATED$
Now, if the field doesnt exist, it will have value $CREATED$, thus the message will be sent to File and not to App System. If the field exists, the message will be sent to App and not to File.
Try that out.
