SAP Web Dispatcher beside SAProuter

[Former Member]

Hello Gurus,

A customer wants to be able to access his SAP apps via web browser. Essentially the same as he can do while using SAPgui.

The path is Internet -> SAProuter -> SAProuter -> SAP-App. This connection works fine and is productive.

So, is it possible to "translate" the used SAProuter-String in SAPgui into a valid web browser link? http://saprouter:8000;saprouter2:8000;SAPapp?

I know that SAP can do this with a specialised brwoser of theirs.. and I also heard that for this I would need the SAP Web Dispatcher. Is this correct? Can SAProuter and Web Dispatcher run on the same server? Do I have to install it on both SAProuters or only on the first one (with public IP)?

Thanks in advance.

Indeed SAP support has special software that they use to access customer's systems through one or more saprouters. As far as I know the solution is not based on Web Dispatcher since SAP can't control customer Web Dispatchers, their existence nor their configuration. Someone from SAP support maybe could share the details of the implementation. I'm guessing it works so that the local browser connects to the local software acting as an server which then routes the request to the designated saprouter(s) using the saprouter string. In your scenario I would install Web Dispatcher on both saprouter servers. In the backend system you should use HTTPURLLOC to generate URLs to point to the first Web Dispatcher which will then connect the second Web Dispatcher which will then connect the backend system.

First of all sorry for the long delay. And thank you very much.

Glad to know that it is possible what I want to do.

Could you please tell me in more detail how you would solve my case? the only information I found is this: https://help.sap.com/saphelp_nw73ehp1/helpdata/en/b0/ebfa88e9164d26bdf1d21a7ef6fc25/content.htm

which is really similiar to my case but not the same. Among other things I dont get how I should commit 2 URLs, first URL to first WD and second URL to my goal system. My second WD should according to second URL and Port connect me to my SAP-system (like saprouter with routtab).

You have to use Cascading of Web Dispatchers, see SAP note 740234 for details.

Thank you. One step closer to get this.

You don't coincidentally have a step to step / guide on how to cofigure a cascade of web dispatchers? The mentioned note does not work for me.

No I don't and I don't remember seeing one. It should be straight forward though. The biggest difference between cascading and normal setup is that you use a configuration file in the first Web Dispatcher to indicate how to connect to the second Web Dispatcher. The configuration of the second Web Dispatcher is normal. What is the issue you are having with applying instructions given in SAP note 740234?

I am new to SAP.

Basically my first web dispatcher is running on a MS server which does not have a SAP-System running. Where is my configuration file? What do I have to configure to point it to my other web dispatcher?

Installing web dispatcher on my sap-systems requires inputting values of my sap system afaik. Where do I find them? I can not find all mentioned .icr files. They are not in my web dispatcher folder.

My biggest problem is I can not implement the provided instructions as I do not know how to and where to find the needed informations.

Sorry, I can't give you hands on advice. You better contact SAP or a SAP partner to get assistance from an experienced SAP basis consultant. The only questions I can answer are: 1) no settings are required in the SAP system in order to install web dispatcher 2) you need to create the files referenced in SAP note 740234 on the first web dispatcher, reflecting the setup of your second web dispatcher. The second web dispatcher needs to be configured against the message server of your SAP system, that is the standard configuration.
