Getting records with highest value in identifier, based on part of the identifier

Posted on by SP_Ontwikkelaar

I have a Sharepoint list Test and I want to put only the most recent records of each project in a gallery.

The list looks like this, the first 4 characters of the identifier is the project code:

and wanted result is

I made a collection col2 by

ClearCollect(col1,SortByColumns(Test,"Identifier",Descending));
ClearCollect(col2,AddColumns(col1,"Project",Left(Identifier,4)));
ClearCollect(colLatest,GroupBy(col2,"Project","Rest"));
Set(NumberOfProjects,CountRows(colLatest));

but then I have to use following instruction to display the values in the gallery [Items:SortByColumns(FirstN(colLatest,NumberOfProjects), "Project")]:

First(ThisItem.Rest).Identifier&"-"&First(ThisItem.Rest).Field1

Can I put the first record of the embedded table of each record directly in the gallery (or a collection)?

Hi @SP_Ontwikkelaar ,

Try the below

With( { wList: AddColumns( Test, "Code", Left(Identifier,4), "Project", Value(Right(Identifier,8)), "FullCode", Identifier & "-" & Field1 ) }, ClearCollect( colLatest, DropColumns( AddColumns( GroupBy( wList, "Code", "Data" ), "Latest", First( Sort( Data, Project, Descending ) ).FullCode ), "Code", "Data" ) ) )

The solution you gave is GREAT, thanks a lot!
I've changed a bit so the result is a record subset of the whole list (= containing several fields) with only the highest values and but with the same definition of fields, so both the list and the collection can be used in _one_ gallery, depending on the whishes of the user.

ClearCollect(col1,SortByColumns(Test,"Identifier",Descending)); With( { wList: AddColumns( Test, "Code", Left(Identifier,4), "Project", Value(Right(Identifier,8)), "Identifier_", Identifier, "Field1_", Field1, "Field2_", Field2 ) }, ClearCollect( colLatest, DropColumns( AddColumns( GroupBy( wList, "Code", "Data" ), "Identifier", First( Sort( Data, Project, Descending ) ).Identifier_, "Field1", First( Sort( Data, Project, Descending ) ).Field1_, "Field2", First( Sort( Data, Project, Descending ) ).Field2_ ), "Code", "Data" ) ) )
