If you have not read the series introduction, I will highly recommend that you do. It discussed the three factors that causes delegation warnings.

In this post, I will explain how to delegate the filter function to SharePoint on the Person/Group column.

Note: What I will discuss here applies to the PowerApps LookUp function as well.

The Person/Group column is of the complex type. Delegation of complex types in SharePoint is done by deferring the decision for delegation to the subfield involved. For Person/Group column, the Email and DisplayName are the only delegable subfields in this data type.

Within the Filter functions, the only delegable operator supported for the delgable subfields is =. This is because, these subfields are Text type, which has the = operator as the only delegable operator.

Expressions in the filter functions can be joined with And or Or, and they will be delegable to SharePoint.

If you want to compare the subfields, do so using constant values that are the same across all records, such as control properties and global and context variables.

With all this information, let’s look at some examples.

===== Useful Information =====

  • Set(UserEmail,User().Email)
  • MyList: SharePoint List
Filter(MyList,Author.Email = User().Email)
Filter(MyList,Author.Email = UserEmail)
Filter(MyList,Author.Email = “name@example.com”)
Filter(MyList,Author.Email <> UserEmail)
Filter(MyList,Author.Email <> “name@example.com” )
