Thanks in advance,

in WE81 we create new logical message type like orders etc.

In we82 we will link the newly created extension with the message type.

In bd57 we can see wat all the communcation idocs posted to which target both sucess & failure

A lot

WE81 is to just create logical message types.

And WE82 is to link logical message and idoc type.

BD57 :Link Type and Serialization Type of Message Type

[amit_khare]

bd54 creation of logical system

scc4 assignment of logical system to client

sm59 communication layer

we81 creation of message type

we31 creation of segment

we30 creation of idoc type

we82 link between idoc type and message type

we 21 creation of port

bd64 CDM

WE57 or BD57 message type and function module through
