Hi Experts,
I have created instances from the SAP Application Server ABAP 7.4 SP5 incl. Business Warehouse on SAP HANA 1.0 SP7 [Developer Edition] free trial solution, as it is described in documentation. As I cannot log on to the Frontend instance (posted a separate question for this) I have tried to reach the servers from my laptop directly. But I cannot create ABAP Project in SAP HANA Studio. While it is trying to connect to SAP, the following message can be seen: Retrieving compatibility information from back-end system, and then the result is an error message: Logon to system A4H failed (Connection to system "A4H" is currently not available). Then in the event details among others there is the following line : (102) JCO_ERROR_COMMUNICATION: Connect from SAP gateway to RFC server failed..... timeout during allocate...
I have a 64-bit Windows 7 version with the required DLLs VS2010.
What I have done so far:
First I have created an instance with the Public options, but I faced the error above. Then I have created a new instance as a Corporate Network. The result is: I can logon to Open VPN client, I can ping the server. I can logon into the system on OS level , both systems are running. I can logon to SAP with SAPGUI. On AWS I have opened all ports for this instance. Then I updated my JAVA, I uninstalled version 7.2 of HANA client and Studio and installed the 7.0 version. Just for a test, I have also switched off Firewall and the AntiVirus program, still nothing. I can reach the HANA DB from the HANA Studio. I have also tried with other laptop running a 32-bit Windows, and faced the same problem. From this laptop I am able to create an ABAP project in another SAP BW System (this one is not in AWS cloud).
I would really appreciate some help.
Thanks,
Andrea
