Hi Niall,
After deploying the designer packages into the MWS,
Goto
Administration → Administrative dashboard → Configaration → CAF Application Runtime Configuration
If you search there, you will find the all deployed projects in that server
Click on project for which you want to change the environmental variables(end point url, username, pwd…)
There you ll find Environmental entries, in that u can change
Hope this will be helpfull.
Regards,
Sunil_N
