Dynamics 365 CRM Portals: Use metadata to set the value of a lookup

As of 21/2/2018 you can now use metadata to set a lookup value on save/submission of a web form step. This is as per release 8.4.0.275. You can find more info here.

It’s very simple stuff. Create a web form metadata record.

Type = Attribute
Attribute Logical Name = The lookup you want to set the value of
Set Value On Save = Yes
Type = Value and Value = The Guid of the record on the other end of the N:1 relationship.

Below is my example from the video where I populated a look up on case where the primary entity was webform, allowing us to know which web form created which case.
