Best way to create a sequentially numbered ID in a column

I have this code below that I've been working on that is copying some records from one place to another. The collection the data is coming from does not have a unique identifier, yet the table I'm patching needs a unique ID.

My current code for QID below only results in a value of 1 for all patched records. What I'd like to happen is if I patched 6 records I want the QID to be 1,2,3,4,5,6 respectively.

How do I get each loop of the ForAll to write a +1 QID?

ForAll(colAssessments, Patch(TempQuestions,Defaults(TempQuestions),{AssessType: colAssessments[@AssessType],Category: colAssessments[@Category],QuestionText: colAssessments[@Question],QID: Max(QID) + 1, A1Text: colAssessments[@A1],A2Text: colAssessments[@A2],A3Text: colAssessments[@A3],Timestamp: Text(Now()),User: User().FullName} ))

Btw... I've seen this video linked in another post, it didn't work for what I'm trying to do. https://www.youtube.com/watch?v=plKw_xfVfwY&feature=youtu.be

Hi @krickard ,
Please try the below - I hope I have the brackets and commas all in the right places.
Clear(colAssessNo); ForAll( colAssessments, Collect( colAssessNo, Last( FirstN( AddColumns( colAssessments, "IDNo", CountRows( colAssessNo )+1 ), CountRows(colAssessNo)+1 ) ) ) ); ForAll( colAssessNo, Patch( TempQuestions, Defaults(TempQuestions), { AssessType: colAssessNo[@AssessType], Category: colAssessNo[@Category], QuestionText: colAssessNo[@Question], QID: IDNo, A1Text: colAssessNo[@A1], A2Text: colAssessNo[@A2], A3Text: colAssessNo[@A3], Timestamp: Text(Now()), User: User().FullName } ) )

Hi @krickard ,

First to define the initial value in the collection and plus 1 in each ForAll loop. Please try this:
ClearCollect(No,1);
ForAll(colAssessments, Patch(TempQuestions,Defaults(TempQuestions),{AssessType: colAssessments[@AssessType],Category: colAssessments[@Category],QuestionText: colAssessments[@Question],QID: Last(No).Value, A1Text: colAssessments[@A1],A2Text: colAssessments[@A2],A3Text: colAssessments[@A3],Timestamp: Text(Now()),User: User().FullName});Collect(No,1+Last(No).Value))

Hope this helps.
Sik

Hi @krickard ,
You might try mine as well - I spent some time testing it and it works.

Thanks @WarrenBelz and @v-siky-msft

@WarrenBelz for some strange reason the code you provided gives me the same "expecting Text... got Table" error that we saw in the last thing you helped me with (link to that post). I tried the same trick that worked before, creating a new canvas app enough to support the code and copying the working button over to the existing app where it was receiving the error... but this time no luck, it still received the error in the new canvas app.

When trying @v-siky-msft's code it works and doesn't receive the error as I stated above. I'm not sure what would cause one to work and the other not work, especially when @WarrenBelz tested this to work on his end.

OK @krickard ,
I could only test the first bit to prove you got your original list with a sequential column added. I could not test the rest of your code as I have no vision of your data structure or control content.
Out of interest have a look at colAssessNo and see what types of fields (text etc are there).They need to line up with your data structure.

@WarrenBelz yes you are correct. It looks like the issue is that the column names for A1, A2, A3 in Saved Assessment are different than A1Text, A2Text, and A3Text in TempQuestions. Once I align the column names your code works.
