I have a customization in Request New Vendor Location form. I have set a constraint where Location needs to be entered when Approving a Vendor Location request. This is getting triggered when the approver Rejects or Returns the request as well... what is the LPL syntax to identify what action was taken by the approver? If I know how to identify the approver action, I can add it to the condition to trigger the constraint only when the approvers approves. What is the LPL syntax to identify the Approval action by approvers in LPL?
