How to save credentials after add a data table from a Oracle Database

[Andres Calvo]

I forgot to check the box "allow to save credentials" when I was adding a table for a fairly complex tool that I'm developing at my work. This is a common problem that I usually fix replacing the date but in this case I notice my mistake after a lot of connections and calculated columns before so I want to know if there is any step to fix it. I already try to do it by edit > data connection properties but in this case the box just show empty. Thanks!
