403 Forbidden Error for Web Dynpro App in Fiori Launchpad

[former_member253610]

Hello,

I am trying to configure My Bank Account Worklist Fiori app. I am getting 403 error when I open the app from Launchpad. As I can see it is trying to access the following service:

/sap/bc/webdynpro/sap/WDA_FCLM_BAM_WORKLIST

But I think this is wrong. It should go through

/sap/bc/ui2/nwbc/

and get the app from backend.

I think something wrong in frontend system configuration.

We already created S4FIN_HTTPS connection and assigned "/sap/bc/ui2/nwbc" as prefix.

Is there anything else we should configure for accessing web dynrpo apps in Fiori Launchpad? Other Fiori apps are working fine. We only have problem with web dynpro apps.

Hi Efecan,

I understand your issue. Did you try activating (/sap/bc/webdynpro/sap/WDA_FCLM_BAM_WORKLIST ) this service in sicf?

I have also implemented the same app and it is working absolutely fine. I have activated both the services below and both are required for the app to work. You still need the webdynpro component (WDA_FCLM_BAM_WORKLIST) to be activated.

/sap/bc/webdynpro/sap/WDA_FCLM_BAM_WORKLIST --- Activating this service should help your app to work.

/sap/bc/ui2/nwbc/ -- This is a general UI2 service not specific to the app and this should be activated as well.

/default_host/sap/bc/icf

/sap/public/bc -- Check if the relevant services in this path is activated as well.

In addition to this follow the below note to complete all the settings, however i am afraid if this will solve your issue as this setting is to get the tile in launchpad designer. Anyways please double check this as well.

S4FIN_HTTPS connection setup is in point 2 however please make sure you are following other points as well for maintaining the relevant system aliases and replicate the app descriptors.

Jay

Hello Jay,

Thank you. I followed most of the steps in the document. Since it is a standard app tile, I am using its standard tile and target mapping as reference. When I press the tile in Launchpad, it opens a new tab and shows a 403 error. I checked the network traffic and it is not going through /sap/bc/ui2/nwbc/ . That is the problem actually. I have to configure the system to use /sap/bc/ui2/nwbc/ path for webdynpro apps.

I have the <system_alias>_HTTPS connection. I tried with and without /sap/bc/ui2/nwbc/ prefix. Is there any other setting I have to configure in frontend system?

Hello Aziz.

Our problem is the app request isn't following the path /sap/bc/ui2/nwbc/ like it says in the note . I want to make it follow this path. We have a problem in system configuration I think.
