Delegation issue in Dataverse filtering looked-up data

Posted on by MalyMajo

Hello,

I am facing issue querying through data in my canvas app. There are 2 Dataverse tables - 'Projects' and 'Assignments' (see examples at the bottom).

Here is a scenario:

I am logged in to the app as User().Email = 'support2'. This means, that I am supporting projects 'Project1' and 'Project2'.

When I open app, I want to see all the resources assigned to the projects, where I am assigned.

So the formula in Items of Resources gallery, looks like this:

Filter(Assignments, User().Email in LookUp(Projects, ProjectName = ProjectName).SupportTeam)

Is there a way to make this delegable? Assignments table contains 2000+ rows.

Projects table

ProjectName	SupportTeam
Project1	support1; support2; support3...
Project2	support2; support4; support5
Project3	support6

Assignments table

Resource	ProjectName
resource1	Project1
resource2	Project1
resource3	Project2
resource4	Project3

Hi @MalyMajo

Create a collection on app start to store the projects supported by the logged-in user. This is a one-time operation and will not be affected by delegation limits.

// On the OnStart event of the app
ClearCollect(
ColSupportedProjects,
Filter(
Projects,
User().Email in SupportTeam
)
);

Use the created collection to filter the Assignments table. Since the collection ColSupportedProjects will have all the projects that the logged-in user supports, you can use it to filter the Assignments table.

// Items property of the Resources gallery
Filter(
Assignments,
ProjectName in ColSupportedProjects.ProjectName
)

Use AddColumn function also

Filter(Assignments, User().Email in
LookUp(
AddColumn(
Projects, ProjectName,prjna),prjna = ProjectName).SupportTeam
)

Thanks!

Hi @Rajkumar_404 ,

second formula (Items property of the Resources gallery) is non-delegable due to 'in'.

Re: Delegation issue in Dataverse filtering looked-up data

Ok, seems like the second formula was delegable in the end, but combination of LookUp with in is non-delegable.

We have found a workaround, where we patch the project data to assignments table when resource is onboarded. It is not the best solution in terms of data redundancy, but it works.
