Cross Reference tool in PowerApps

Hello everyone,


I have a list in SharePoint  with around 300 learning objectives (LO). The columns in the list are LO, LO Description, Event, Lesson, PPT Title, PPT Page#, Source Document, and Section


LOs are covered in multiple lessons and events, and events can cover multiple LOs, so there are over 1000 items in the list.


Here is a sample of the list:

I want to build a cross reference tool in PowerApps which will enable me to enter the training event, for instance "NH4", and have the tool list all of the LOs, lessons, and source documents associated with that event.  Or I want to enter the LO and find out which events, lessons, etc. cover that LO. See example below:

Below is a diagram of what I want to get to. Where, if the either the LO #, the Event, or the Lesson code is entered, the fields below would populate



______ Learning Obj  (LO)   _NH4______  Event      ______ Lesson 


40 LO /     Clearance      LO Description / NH4  Event / COM11 Lesson / INDOC NH4  PPT Title / 15  PPT Page # / EHB Source Document / 500  Section

You can use a filter expression that will use the values that were entered in the text inputs, like the one below.

    txtLO.Text = "" Or LO = Value(txtLO.Text) Or LODescription = txtLO.Text,
    txtEvent.Text = "" Or Event = txtEvent.Text,
    txtLesson.Text = "" Or Lesson = txtLesson.Text)

You can use the attached app to see this formula being used.

Hi @ewchris_alaska,


How do you display your learning objectives within your app? Using Data table?


I agree with @ewchris_alaska's thought almost, I think the Filter function within PowerApps could achieve your needs.


I assume that you use a Data table control to display the learning objectives within your app, please set the Items property of the Data table control to following formula:


Note: The TextInput1, TextInput2 and TextInput3 represents the TextInput control, you could separately type your LO value, Event value and Lesson value within them.


In addition, you could also take a try with the following formula:
