powerapps filter table based on value from another list

I'm trying to filter a list which contains "status details". I want to display the all of the status details which are connected to the selected issue record. Where "Ticket #" = the "ID" (ticket# = field in CV Status,  ID=the primary key of the record in CV issues and enhancements). 


A few things to note:

The CV status table is in a DataCard - should this be in a Gallery?

The field Ticket # (in CV Status List) is a drop down field pulling from the ID field in the CV Issues and Enhancements List


Here is the formula I'm using, but its not working:

Filter('CV Status Updates', 'CV Status Updates'.'Ticket #'='CV Issues and Enhancements'.ID)

- I'm getting an error which says "The filter part of this formula may not work correctly on large data sets"





Thanks in advance

Sounds like your Ticket # field is a LookUp field in SharePoint, is this correct? I avoid setting up these field types (ie ALL Complex columns, Choice, LookUp, Calculated, etc) for any lists that I intend to use with PowerApps - they are just so buggy, and restrictive, as you have discovered.


For a fix, you may be able to set your 'CV Issues and Enhancements'.ID to a variable then use that in your formula, eg


Filter('CV Status Updates', 'CV Status Updates'.'Ticket #'= someVarName)

// where someVarName is the ID value matching Ticket #


It's a little hard to tell how to set this variable because I cannot see the flow of your app, ie how you are getting other data in. I can help further with that, if need be, if you explain your app a little more.


Thank you for the response. To troubleshoot my issue, I did create another field which I manually typed in the Ticket #.   

Filter('CV Status Updates', 'CV Status Updates'.'Ticket #'= someVarName)

in your formula - the field in the "Status updates" table, needs to match the value of the ID in the CV Issues and Enhancements table. How would I write that? The ticket number is simply the ID record in the CV Issues and enhancements table.

Can you tell me what types the fields 'Ticket #' and 'ID' (from CV Issues and enhancements) are. Are they both LookUp columns?

I noticed an issue with using the correct tables (I had the same table in a different MS Team for testing). This is fixed. 


  • Ticket # (number) - this is manually typed in
  • ID is the primary key in the CV Issues and enhancements table


If I were to create a variable for the ID field in the Issues and enhancements table - where would I define that? 

Its strange that I can't apply any filter to the table


This is what  I'm thinking for the 2 formulas:

Set(varTicketID, 'CV Issues and Enhancements'.ID)


Filter('CV Status Updates','Innosabi Ticket'= varTicketID)


Thanks for your help

So you are using Teams for your app, is this correct? Meaning that Dataverse is your data source? I don't have a lot of Dataverse experience but I do know that LookUp fields are tricky to use in that they need to be referenced differently. 

I appreciate your help. I'm still stuck. I have everything in sharepoint. If I were to define a variable with the ticket # - where would I define that?  This seems like a basic filter - I can filter based on a static # ie: 1 but when I try to refer to another field, it doesn't work (delegation issue). The table is only about 97 records.  




Not applicable


Just so I understand your situation, please confirm that your setup is as follows:

- List 'CV Issues and Enhancements' holds Ticket numbers (ie 'ID') and there is one and only one Ticket number

- List 'CV Status Updates' has a LookUp column called 'Ticket #' that references ID in the above table

- This LookUp column is set to NOT allow multiple values ie Single LookUp


If the above is correct you should be able to do something like this


    'CV Status Updates',
    'Ticket #'.Value = TextInput1.Text

// where TextInput1 is a Text Input control. 


Your initial formula doesn't have a reference to a Ticket number and you need one so you can filter the 'CV Status Updates' List, hence why I'm using a TextInput field. You can also use a reference from click an item in another gallery or some other way but you need a reference to filter the Status list.


I'd also recommend using a Gallery over a Data Table, unless you are just wanting to view the results. Galleries give you far more UI flexibility but if you don't need that then a Data Table will be ok.

Sorry for the delay - thank you for your continued help on this. I see where you have "TextImput.1.Text" - shouldn't this be a "whole number" ? Because Ticket is a number value. Would it be better to have this as a text value? 




Not applicable


You can just wrap that in the Value function to force the text to number data type, ie




You can also enforce entry of numbers only into the Text Input field by setting the Format property to TextFormat.Number
