Root Cause:

The error indicates that the SAP Gateway rejected the registration of the CUSTOMERCECP1 program from the Adeptia server at 10.*.*.* due to a missing or misconfigured entry in the SAP Gateway’s reginfo file.

Suggested Solution: 

The following entry resolved the issue in the SAP Gateway configuration:

P TP=CLOUDECP HOST=10.0.0.0/20 ACCESS=* CANCEL=*

Explanation of Parameters:

• TP=CLOUDECP: Specifies the registered program name expected by SAP Gateway.
• HOST=10.0.0.0/20: Defines the allowed IP range. Must match the IP address of the proxy client attempting registration (10.*.*.* in this case).
• ACCESS=*: Grants registration access to all users. (This can be tightened based on security requirements.)
• CANCEL=*: Permits deregistration by any user (can also be restricted for security).

This entry was added to the reginfo file by the SAP Basis team to permit the connection and resolve the registration denial error.
