Summary

Invoke HCM Self Service transactions from DCS portal using deep links

Content

Am using ${AlertUtils.getURI('ORA_HCM_UIAPP','hcmUI/faces/deeplink?objType=CHANGE_ASSIGNMENT&action=NONE')} to get the URI from Engagement Cloud,. This is working fine.

I am trying to achieve the same from DCS Portal. I have created a hyperlink with href as something like below

https://example.com/hcmUI/faces/deeplink?objType=CHANGE_ASSIGNMENT&action=NONE

but when i click the hyperlink it is taking me to a blank page where nothing is loaded on the browser page.

How to achieve this from DCS portal?
