Demo scenarios not working in ABAP Developer Trial

Hello all,

I want to learn about new technologies like Fiori, so I've configured the Developer Trial version on Amazon Web Services (AWS).

"SAP NetWeaver 7.50 SP1 AS ABAP and SAP BW on SAP HANA SPS10 - Developer Edition"

I am using Remote Desktop and from there I can logon to SAP GUI. My problem is that no Web based Scenario is working, because the Browser can't reach the URL. For example when I try to call the demo of "SAP Fiori Launchpad" (Transaction /UI2/FLP) I get the message "Page can't be displayed".

I've called transaction SICF to see if I can call any other Web based application like one of the WDA demos, but it is still not working even though the SICF services are active. In the "Getting Started Guide" it was mentioned, that the Browser Proxy settings has to be done correctly but there are no instructions how to achieve that.

Can anyone tell me how to configure the browser proxy?

Kind Regards

Hi Mark,

For Chrome, here are the instructions:

  1. Open Google Chrome. It's a red, yellow, green, and blue sphere icon.
  2. Click ⋮. This icon is in the top-right corner of the page. A drop-down menu will appear.
  3. Click Settings. It's near the bottom of the drop-down menu.
  4. Scroll down and click Advanced. You'll find it at the bottom of the page.
  5. Scroll down and click Open proxy settings. This option is in the "System" group of settings that's near the bottom of the page.
  6. Edit your proxy settings. Depending on your operating system, this step will vary: Windows - Click LAN settings, then edit the URL in the Address section and/or change the port used to connect in the Port section. Mac - Select the proxy you want to edit on the left side of the page, then change the URL in the Address field, the username and/or password in the Username and Password fields, and the bypassed sites in the Bypass field.
  7. Select Manual Proxy configuration option. Enter your HTTP Proxy and Port value (e.g. proxy and 8080). Select Use this proxy server for all protocols option
  8. Click OK, then click Apply. Both are at the bottom of the respective windows. Doing so will save your updated proxy settings.

Thanks,

Ron Nero

Hi Ron,

thank you for the detailed description of how to change Proxy settings in Chrome. I think I haven't made myself clear enough.

I am just guessing, that this is the problem why I can't call WebDynpro and Fiori transactions in the Development Trial. But maybe somehting else is causing this. If this is really the Proxy issue then I still don't know what to enter in the Proxy settings. I don't know which port to enter and i don't know the IP of the proxy.

Kind Regards

I checked in my browser (FF) and there is simply an option to use "system proxy". I've never had to enter a proxy manually, not sure why this would be required in this case. Otherwise Google "http proxy where to find" might be of some assistance.

Edit: it'd be helpful if you've posted a link to the specific "Getting started guide" in question and pointed out where it talks about proxy settings.

Hi Mark, hi Jelena,

(I will address the actual problem later.)

The guide is this one:

Getting Started: SAP AS ABAP 750 SP02 on ASE 16

but it's not helpful in this case. It just says "To access the linked guides please ensure correct proxy settings (see solution guide) and use Firefox for running the sample applications."

There is no link to the solution guide. I am trying to find out who wrote this sentence and to what they are referring.

For your actual problem, please see below (I don't want it hidden in these nested comments).

Best wishes Julie.

Hi Mark - if you want to explore SAP Fiori, then this would be a much faster option: https://www.sapfioritrial.com

Hi Jeremy, hi Mark,

I'm just going to expand on your answer. I think it depends what you want to do:

1. You want to develop SAP Fiori / SAPUI5 apps => then do as Jeremy says.

2. As for option 2, you want to develop SAP Fiori / SAPUI5 apps, but based on CDS views or ABAP Dictionary (DDIC) objects, plus OData services, that you have created yourself. HOWEVER, you don't want to spend time configuring a local system. => You can use the preconfigured Cloud Appliance, as you are doing.

NOTE: I recommend 7.51, not 7.50, in that case: https://www.sap.com/developer/trials-downloads.html - just scroll down.

( Jeremy Good - is this also possible in https://www.sapfioritrial.com ? Please correct me, but I thought not.)

Regarding your actual problem: Please try what Ron has suggested and let me know.

Best wishes,

Julie.

It looks like OP just doesn't know what to put in the proxy settings. And TBH I'm not very clear myself why proxy settings in the browser would even need to be touched here.

Hi Julie Plummer - your hyperlink to my profile didn't alert me like an 'at-mention' would, so I just stumbled upon this comment (wasn't ignoring you on purpose). The answer I offered was simply to shortcut the exploration of SAP Fiori on the front-end server running in SAP Cloud Platform, since this comes with pre-delivered apps and guided help for extensions with Web IDE, and demo data in a back-end system. The NW GW version is less of a concern, since it primarily gives you an environment to further explore with instant gratification. If the back-end system supports annotations and CDS views, then the front-end server and apps should happily consume them, and Web IDE provides wizards and templates for this. I'm no expert on on the granular details, but I'm under the assumption that if you use the cloud connector to expose your own GW system, then the same SAP Cloud Platform front-end server with Fiori launchpad and SAPUI5 apps would work perfectly well. And just for clarification, the www.sapfioritrial.com site is not the SAP Cloud Platform 'trial' site with all the beta services, etc.

Hi Mark,

I may or may not be able to help. However, the good (?!) news is, I am currently testing 752 (ASE, but same principle) on CAL , and encountered the same problem. (I'm not using a proxy.)

I solved it by adding the following my hosts file in Windows/System32/drivers/etc/hosts (edit as Administrator):

#CAL : Internal Test : 752 SP01 ASE

<ip address> vhcala4hci vhcala4hci.dummy.nodomain

NOTE: For HANA the address is vhcala4hci ; for ASE it would be vhcalnplci

I got an error "Your connection is not private." If you get that, choose Advanced, then Proceed. If you get the same error and can't proceed, then that is an issue specific to your landscape.

You can get the IP address from the home page of your instance in CAL. NB : Application Server, NOT Frontend Server:

Apologies if you've tried that already. Next steps are actually described in the guide, ch 7, Troubleshooting:

Symptom: You can’t connect to your backend instance using your local SAP GUI.

1. Check if the ABAP server is running:

2. Logon as root to the server on which the database is running (see Connecting to Your Backend on OS Level). Then execute the following statements to check the status of the ABAP server:
su – npladm
sapcontrol -nr 00 -function GetProcessList

3. Check if all required TCP ports are open and accessible from your local network.

If that fails, then we can revisit the proxy issue.

Best wishes Julie.

Hi Julie,

thank you for your help.

I've already deactivated the EC2 Instances, because at this time it was not worth the monthly cost and currently I am working on a S/4 HANA Project, so that I have access to a real system.

Kind Regards
Mark André
