Sending FICO Documents via Idoc

Currently, we are sending the recon data to the partner system using FPG4 and then FPG1.

We use the Idoc - FIDCC1 and basic type FIDCCP02 to send the FICO details.

We are also posting many documents and intercompany documents directly via FB01.

I am trying to seek some help on how do we transfer these documents to the partner system.

Appreciate your assistance.
