In C4C on SDK we have a custom solution "A" in which we created a field(element) on Opportunity root node.
We would like to use this element in a different custom solution "B" in the "BeforeSave" method of the root node of an opportunity. However SDK throws an error that it doesnt recognize this element. Also doesn't show up in the suggestions list.
I have tried to add .ref file to customer fields but I do not find this field in it. I believe it only shows custom fields created in KUT.
So my question is do you know how can I access this customer field in solution "B" ?
