why we have to create receiver communication channel for Idoc adapter?

[Former Member]

Hi Friends,

While configuring the communication channel for Idoc adapter sender CC is not necessary but receiver CC is necessary.

But Idoc resides on abap stack ,why exception for sender channel and why necessary for receiver channel.

I think this might be the reason.

PI work as one client. ex 001. So ECC push the message to Integration Engine directly. In this case we dont need communciation channel. When mesg sends from PI to ECC, we need to associate business sytem (ABAP) with appropriate ECC client number. So we use IDOC receiver where we mention RFC Destination corresponds to specfic client of ECC SAP System. Basically RFC Destination make sure to send the mesg to appropriate client of ECC SAP system

Hi Raj,

From PI point of view, Messages should come in or go out with through communication channels.. Communication channel is like a medium for communication... In communication channel we will specify the format of adapter type i.e., format of message to be transferred. so In IDOC to FILE scenario we are using receiver communication channeel.. For IDOC no need for communication channel since it passes from abap side.. also we use RFC connection to transfer the message.. We use communicationn channel only for PI part..
