I have a master table Client.
I have a details table Merchant Accounts (MIDS for short).
One Client has 1-to-n MIDS.
Client has a multi-select field: Services
My goal:
- Based on the value of Client - Services, hide a field in MIDS form.
What I've done so far:
- Define 1-to-n relationship from Client to MIDS.
- Added Client - Services as a lookup field.
- Client - Name by default was added as a lookup field and a reference proxy.
- MIDS Main Form, tried adding a dynamic rule based on Client - Services lookup field.
- I get an error: "There are no compatible fields".
Here are the screenshots:
