Question:
Can anybody let me know what is the difference between ABAP port, File port and t-RFC port ?
Answer:
Hi,
I believe that ABAP port should not used for interfaces !!!
File port as it's name indicate is used to downlod/upload files (IDOCS) on a logic or physic path.
T-RFC port is a transactionnel port used to send/receive IDOCS from others R/3 or Systems like SAP Business Connector using RFC technologie (Remote Function Call).
I hope it's clear,
