I am trying to add Lookup field (account) on contact form. I know that previously this was not supported but now it is mention in spring update that it can be done.
If It can be done, how can I use this?
Screenshot of where it is mention:
The spring update provides support for SQL Views. In your case, this would enable you to build a SQL Server view that joins your Contact and Account tables. The benefit of this is that it allows you to display Contact and account details in a gallery (or other list control) without the performance overhead of carrying out the account detail lookup for each record from within PowerApps.
For data entry purposes, it's possible to build screens with lookup fields. For instance, if you want to add a drop down control to a contract entry screen that enables a user to select an account, the answer in my post here might help you.
This article on the PowerApps blog describes how to use this feature.
Can you explain what exactly doesn't work?
There is now a new version of CDS which might be the cause of the problem, but the CDS has always supported lookups.
The following link describes...
>> If you create an app automatically from an entity that contains a lookup field, it appears as a Drop down control that contains data from the Primary name field of the entity.
