The Replacement Variables table is a background table that can be used to support any of the process tables, such as Approvals, Contracts, Projects, or Tasks. Replacement Variable records store a variable chain used to pull in values from a linked field relationship. Generally, these variables are copied into template records (e.g., in the Approval Templates table) and then used to dynamically assign records or set other field values when a process table record is generated from a template.
Replacement Variables are used by Approval Templates to generate Approval records for contracts, change requests, documents, or service requests.
To create a Replacement Variable that will be used in Approvals, set Used In Field to the value "Approval Assigned To". The value in the List Value field will shows up in the Assign To drop-down in an Approval Template. Last, create a variable chain from the Approvals table to the appropriate field variable. For example, $contact_id.requester_name finds the name of the Requester in the linked Contract record, while $contract_id.requester_id.manager_name finds the Requester's manager.
Caution: The Variable should be a variable chain that starts from the Approval record—not from the Approval Template!
Admin Note: The values "Task Assigned To" and "Other" do not link to any automation in the default setup, but they can be deployed and used with minor modifications to Task Templates or other template table.
