Unable to add Used DC of track1 to the DC of track2
We are having two development tracks based on two different regions DC Track1 and DC track2. In DC track1 I have DC of type Deployable Proxy component and in DC Track2 I have DC of type Portal application. In My portal application DC, which is in track2 I want to add DC - deployable proxy of Track1 however I cant see option to access it in my NWDS. I can only see the Track2 SCs and DCs in the popup while adding the Used DC.
Please let me know how to fix this problem.
