MSS configuration questions

Hello,

I am going round in circles with the configuration of the MSS and maybe someone can help me.

I configured CATS to use an task that leeds to an item in the UWL. This works fine.

The thing I don't get is the following:

Pressing the link to open the task for the time approval the wrong URL is getting called. Regarding this I am wondering where this link comes from. Is it an system (i.e. with the SAP_XSS_WEBDYNPRO alias)? Or is it configured in the task? Where can I configure it and what is the right path to the application? Using the URL myHostToThePortal:myPort/webdynpro/dispatcher/sap.com/mss_catapproval/CatManagerApprove gives the error: The requested deployable object 'sap.com/mss_catapproval' and application 'CatManagerApprove' are not deployed on the server. Should this application be on frontend or backend side?

Thanks in advance,

Vanessa
