Hey, I'm just learning about formulas but, is there a document or something on what functions are allowed? When creating a formula and clicking on the drop down list, some functions are there but it seems to me that some are not i.e. "to_char(systimestamp AT TIME ZONE 'America/Mexico_City', 'HH24MISS')" Where does "systimestamp" or "AT TIME ZONE" come from?

There is a list in help for sure. If you search SQL functions it should be in there for formulas.

Got it, sorry I missed it. Thank you.

In the official NetSuite support forum there is a thread called something like 100 Saved Search formula examples.
