Check Connection of Communication Arrangement for SAP ERP Financials Using IDoc Failed
We are checking outbound connection from C4TE to ERP in Communication Arrangement for SAP ERP Financials Using IDoc Failed.
We get the attached error message:
Checking connection failed
Error accessing service; Service Ping ERROR: Forbidden (403)
What could be the reasons, in ERP side, through Tcode SMICM, we didn't see any log from C4TE side, and we cannot ping the ERP side successfully.
One more thing, in C4TE, we tried to set the connection to an SAP internal ERP system, and the connection was successful. But when relinked to the customer ERP system, connection failed.
Could it be firewalls reason?
