When the Customer column changes on an Item or Expense for a Vendor Bill, the Billable checkbox automatically changes to true. I've tried to find a script or workflow that's making that happen but I haven't been able to so far. Is this native NetSuite behavior and if so, why? If not, do you have any tips on finding out what's ticking the checkbox? There are many situations where we don't want it automatically ticked. I've downloaded all the .js files and all the workflow xml files in the system and run a search for "isbillable" on them, but didn't find anything.

Maybe?

Thanks, I'll check that out!
