I have sharepoint custom list with 3 columns:-

1) ScoreGreenPoint --> of type number

2) ScoreRedPoint --> of type number

3) ScoreFinalScore --> of type calcualted

and inside the PowerApp i am sorting based on the above calculated column, as follow:-

but the sorting is not working for negative numbers!! because -1 (1 green point - 2 red points) is larger than -5 (5 green point with 10 red point)!! any advice?

Hi @johnjohn123 ,

Try to keep away from using SharePoint calculated columns in Power Apps (they will not perform as expected) and do the calculation in Power Apps instead. I would recommend default a number field in SharePoint to the calculation and Patch it with the calculation when anything is changed affecting it.

@WarrenBelzto be honest it is weried that such a straightforward sorting will not work.. so how i can do the calculation inside power app and then sort based on the result?

I tried these formuals:-

SortByColumns(Scores,"ScoreGreenPoint"-"ScoreRedPoint",Descending)
SortByColumns(AddColumns("Scores","ScoreFinalScore",Value(Effect)),"ScoreFinalScore",Descending)

I also created a Label with this formual:-

then i used this formula:-

SortByColumns(Scores,Label2,Descending)

but did not work !

Hi @johnjohn123 ,

I was referring to making the same calculation as the SharePoint calculated column in Power Apps then populating a number field with it (on all records). You would then sort on this column.

What I was pointing out was that there are column type in SharePoint that are really only useful in SharePoint and if referenced in Power Apps cause unwanted hardship. I have done a blog on this if it is useful to you.

@johnjohn123 ,

On second thoughts now I see how simple the formula is, you could use AddColumns() and do this

SortByColumns( AddColumns( Scores, "SortField" ScoreGreenPoint-ScoreRedPoint ), SortField, Descending )
