IDoc Reaches SAP PI but No cXML Message Generated

[rohith_akaram]

I am working on an SAP PI/PO scenario where an outbound IDoc needs to be converted to cXML and sent to our partner’s Boomi endpoint.

My sender IDoc channel is working fine, and the mapping executes successfully.
But the receiver HTTP channel (CC_RCV_XXXX) stays in red status, and no cXML is being delivered to the endpoint. but in Open Message i can the CXML file. and status is waiting with 400 after that it is successful with 401 i

What I see

• The Connection Test in the receiver channel shows “Connection OK.”

• But the channel status in monitoring is red.

• Runtime messages fail before the cXML gets delivered.

• The partner endpoint is reachable and responds in Postman.

What I need help with

Why does the communication channel remain red, even when the connection test succeeds?

What are the possible runtime issues (authentication method, URL format, Content-Type, SSL, mapping, HTTP error codes, etc.) that can cause:

• Ping OK, but

• Actual message delivery failing, causing the channel to stay red?

If anyone has run into this type of issue, please share what the root cause was or what logs I should focus on.

Thanks!
