"Comparing POS Values in PowerApps: Displaying Only One Entry and Syntax Error with ForAll"

Posted on by Ensosim

i have a dataverse table displayed in powerapps. in this dataverse table there is a pos that is unique.
I would now like to compare the pos with the other datasource that I have also included in the powerapps.

If(pos.Text = Text(ThisItem.Pos) , stueck.Text, "")

Unfortunately, it only shows me one item in the piece column.
When I try to use Forall I constantly get a syntax error

ForAll('VK-EK_1', If(pos.Text = Text(ThisItem.Pos) , stueck.Text, ""))

Hello, @Ensosim, ForAll function returns a table not a text value. Also, you can't use the Data table control to calculate values in the Canvas App. If you use a Gallrey, you can achieve this instead.

What type is this other data source? Sounds like you are looking to "Filter" the other data source with "ThisItem"'s value?

The other data source is a json file that I have converted into a table, where I display the individual columns in a gallery.
But I need the same columns with the values in the dataverse table, they should only be displayed there.

I need length width from the table for my dataverse table and a few more columns.

This is the Dataverse Table where i want to display a few columns of the tst.response
pos.Text and stueck.Text are from the tst.reponse. With this if function i get only one row, but i need all rows from the tst. response. The pos from dataverse and the json table are the same. So i thougt i can compare this both to get the correct value

Ok, so that sounds like joining two tables on "pos" column? it'll need a POC to do exact logic, but something like below might be of help?

ClearCollect( JoinedList, ForAll( List1, Patch( List1, LookUp(List2, Id = List1.Id) ) ) )
