Anybody know how I use getValue to reference a column in a saved search that's a numeric formula when I have multiple columns that are also numeric formulas?

That's one of the frustrations that made me move to "N/query" you can create aliases for all the columns and then

run().asMappedQuery()

that gives you a nice array of objects with simple keys you define. You can do it in searches like you found, but it's not nearly as clean.

The problem with using suiteql is that you can't run everything with it (for example some fields on transactions).
