Any way to replicate the concept of a Primary Compound Key on a custom record? I have a custom record (let’s call it “Thing” with about 6 custom fields. Three of them should be the compound key (transaction ID custrecord_tx_id, vendor ID custrecord_vend_id, and a third that points to a different custom record ID (let’s call this custrecord_cr_id)). So for example there should at most one “Thing” where custrecord_tx_id = 1, custrecord_vend_id = 1, and custrecord_cr_id = 1.
