I found this table SuiteScriptDetail that looks very interesting in the context of monitoring script performance. But the table is empty in my account. Anyone know anything about it or actually have some data in the table?

On a side note how did you end up finding this hidden table ? Will check if we have data in this table.

Empty in our account too fwiw

It's not hidden. It is listed in the records catalog, when you create analytics datasets. The help mentions it both in the search.Type and query.Type enums.

how strange. I checked 6 different accounts and that table is empty in all of them. i wonder if its something you have to intentionally write to.

maybe netsuite just created that table and later forgot about it? I can see its empty across all the accounts i have access
