How to test inbound idoc in WE19

Hi Friends,

I have to update few delivery items data for my scenario. The sender is a non sap system.

I have found :

basic type : delvry05

msg type : desadv

process code : dels

Under logical system

===============

Partner profile: SNCF100

TYPE : LS

added my message type DESADV in inbound parameters.

Now I want to check if I can update my item data fields thru this basic type or not.

But when I do a testing thru WE19 it gives me error.

So how to test it with WE19.

What information do i need to enter in Control record

for SENDER and RECEIVER?

kindly guide.

Thanks,

Pradeep
