**Subject: Unable to connect Eclipse BW Modeling Tools / ABAP Development Tools to SAP BW/4HANA 2023

[#1]

Hi everyone,

I deployed a SAP BW/4HANA 2023 SP04 Trial appliance through SAP Cloud Appliance Library (CAL) on Microsoft Azure.

Environment

• SAP BW/4HANA 2023 SP04 Trial
• SAP CAL deployment on Azure
• Eclipse with:
  • BW Modeling Tools
  • ABAP Development Tools (ADT)
• Accessing the system from a local Windows machine

What I have verified

1. Appliance status is Active in CAL.
2. CAL provides a SAP GUI connection with:
   • SID: A4H
   • Instance Number: 00
   • Client: 100
3. Network connectivity appears to be working:
   • Port 3200 is reachable.
   • Port 44300 is reachable.

Eclipse Configuration

For both BW Project and ABAP Project creation, I am using:

• Connection Type: Custom Application Server
• System ID: A4H
• Application Server:
• Instance Number: 00

Problem

Both BW Project and ABAP Project fail before authentication with the following error:

Logon to system A4H failed
(reject connection request from <local_machine>:eclipse to <server>:sapdp00)

The error occurs even before user validation.

Additional Information

• The SAP CAL "Connect" option only downloads a .sap file for SAP GUI.
• I do not currently have SAP GUI installed(due to license that we don't have), so testing via SAP GUI is not yet possible.
• The error is the same regardless of the SAP user entered.

Questions

1. What does "reject connection request ... sapdp00" typically indicate in a BW/4HANA Trial appliance?
2. Is there any additional SAP profile parameter or dispatcher setting that must be enabled for Eclipse BW Modeling Tools / ADT access?
3. Is connecting through the public VM IP supported for this appliance, or should Eclipse use a different hostname from the SAP system configuration?
4. Has anyone successfully connected BW Modeling Tools to the SAP BW/4HANA 2023 Trial appliance from CAL, and if so, what connection method was used?

Any guidance would be greatly appreciated.
