Posted on by Ycrad

Hi All,

I want to get the last record of each Tag (Only Lines with red cross at the front) and display them in a Gallery. My data are stored in a SP list.

I tried with ForAll loop but i didn't get the expected result.

Maybe someone could help me.

Thx for any help you will bring me.

I think that the only way is this:

Set(varTagsAlreadyIn, "");

ForAll(

Sort(DataSource, ID, Descending),

If(!(Tag in varTagsAlreadyIn),

//IT IS THE FIRST ONE

Set(varNewTag, varTagsAlreadyIn & " ," & Tag);

Set(varTagsAlreadyIn, varNewTag),

//IT IS NOT THE FIRST

)

I am creating 2 vars because you cant self reference in Power Apps.

You can always try with Concat or Concatenate but I am not sure how to do it

Thank you Nogueira 1306 for your response,

But it seems that Set function could not be called in ForAll function. The system returns an error and i don't know why... 😞

@Ycrad

I disagree with the approach. Much simpler without variables:
Use GroupBy(Sort(SPlist,ID,Descending),"Tag","Info") as your Items property of the gallery.
Then inside the gallery put labels with text property as "Tag", First(ThisItem.Info).Posted, First(ThisItem.Info).'Eqpt Name', etc.

Drrickryp,

So, if i want to get between these unique last entries only those match with some criteria as TestStatus="Fail" or TestStatus="Succes" but DateDiff(Created;NextTest)<0 how can i Do?
My Collection is called Lune :
ClearCollect(Lune;GroupBy(Sort(Filter(TestsData;Site=CombSite_2.Selected.Title);ID;Descending);"TagEquipement";"Info"));
When i tried to get the result into another Collection called LuneResult with :
Clearcollect(LuneResult;Filter(Lune;Info.TestStatus="Fail" || (Info.TestStatus="Success" && DateDiff(Created;NextTest)))<0 ;
I don't get the expected result.

Could you help please ?

Thank you.
