How can I remov SAPJAM and add my own destination

Hi All,

First time I am trying with RDE and when I try to set up using the following how to guide

Set up your SAP River RDE on HANA Cloud

I can't seet he desitnation I created rather than I am getting SAPJAM, and it can't editable for me.

What is the way to go further

Thanks

Rajesh
