Help with dropdown lookup on foreign key

(0) ShareShare

Posted on by Community Power Pla... Microsoft Employee

Hi, 

 

I am new to PowerApps and have been trying to work out the following:

 

Drop down list Organisation displays OrganisationName and is linked to Organisation table, which contains fields ID, OrganisationName.

 

Drop down list Employee is linked to Employee table which contains columns EmployeeName, OrganisationID.

 

Organisation.ID = Employee.OrganisationID

 

How do I set Employee drop down so that when I select an OrganisationName in the Organisation drop down, it does a lookup on Organisation.ID against Employee.OrganisationID and shows me only EmployeeName for the selected OrganisationName.

 

Thank you

    You can add a filter to the items property of the Employee drop down to show just the users in the Organisation selected in the Organisation drop down (ddOrganisation).

     

    Example: Filter(Employee, OrganisationID = ddOrganisation.Selected.ID)

     

    This example assumes the Organisation drop down returns a record with the ID and OrganisationName.

    Hi @Anonymous , I don't think the "foreign keys" is not an actual relationship PK and FK diagram you have built in SSMS or SQL right? or do you have 2 separate tables with the same column listed so that it becomes a one to many relationship? in anycase, Filter will work but you might have issues with commands like Patch or during the write into your database.
