Anyone know of a way to access the "Print on Check As" field via a customer saved search? It's available for Vendors, but not Customers for some reason.

It's not an available search column in that record type according to the records browser. You'll probably need to add a custom field on customer records and to copy the value over from the standard to the custom field. Depending on how often customer records change you could do it daily with a mass update, or on change with a user event script.

Or use a not store value field with a formula. But a non store value could be not avaialbe in the saved search too

Print on Check As is available in Suite Analytics. Depending on what your trying to do, that may be an option for you. If you need help getting started with SA let me know.

Thanks everyone, and great tip about SA @Sean Murphy
