Dear MrExcel Lads,

I'm looking for a way to speed up my macro. Current timing varies between 30s if array2 has 500 rows and 2minutes if array2 contains 1500rows.

Case:
- two arrays: arrayInput & arrayAdjustments
- arrayAdjustment is created from a template in one of the sheets and then filled with data by week/keyfigure
- product & keyfigure combinatation is not unique in arrayinput
- product & keyfigure combination is unique in arrayAdjusments
- there are more types of keyfigures in arrayInput than in arrayAdjusments, im interested only in summing up what is in arrayAdjustment
- arrayAdjustments is basically a pivot with additional filtering of keyfigure, but it need it as raw table to process and change later

My current approach is to do it via array loops, is there a faster way? Or a way to optimize my code?
(I'm using a couple of public functions in the code below, but hope the their name will be self explanatory)

VBA Code:
Sub adjSheetFill()


Dim timerAdj_fast As Single
timerAdj_fast = Timer()

Call sharedData.defineVariables

Dim numberColumnKeyFigure As Integer
Dim arrayInput As Variant, arrayKF As Variant, arrayAdjustment As Variant, result As Variant
Dim keyFigure As String, keyFigureInput As String, product As String
Dim rng As range, cell As range, sum As Double
Dim columnKeyFigureAdjustment As Integer, columnkeyFigureInput As Integer, phasing As Integer


arrayAdjustment = Worksheets(sheetAdjustments).range("A1").CurrentRegion.Value       'array with list of desired KF from workspace tab,

Dim r As Long, j As Long, i as Long

            arrayInput = createarrayInput
            arrayInput = addKeyColumnToArray(arrayInput)
            columnkeyFigureInput = findHeaderinArray(arrayInput, headerKeyFigures)
            columnKeyFigureAdjustment = findHeaderinArray(arrayAdjustment, headerKeyFigures)
            columnProductAdjustment = findHeaderinArray(arrayAdjustment, headerKey)
            phasing = columnkeyFigureInput - columnKeyFigureAdjustment

                      
    For r = LBound(arrayAdjustment, 1) + 1 To UBound(arrayAdjustment, 1)
            sum = 0

            keyFigure = arrayAdjustment(r, columnKeyFigureAdjustment)
            product = arrayAdjustment(r, columnProductAdjustment)

            For j = columnKeyFigureAdjustment + 1 To columnKeyFigureAdjustment + periodCountWeeks

            sum = 0

                For i = LBound(arrayInput, 1) + 1 To UBound(arrayInput, 1) - 1
                    If IsEmpty(arrayInput(i, columnkeyFigureInput)) Then
                    GoTo continue
                    End If

                sum = sum + arrayInput(i, j + phasing)
                arrayAdjustment(r, j) = sum

                Next i             

continue:

                sum = sum + arrayInput(i, j + phasing)
                arrayAdjustment(r, j) = sum

            Next j

    Next r


Worksheets(sheetAdjustment.range("A1:AD10000").ClearContents
Call pasteArray(arrayAdjustment, sheetAdjustment, "A1", 0)

Debug.Print "adjSheetFill_fast - end : " & Timer - timerAdj_fast

End Sub

Excel Facts

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.
This may take a few goes to get right, but here's a start. Try the following code on a copy of your file.

VBA Code:
Option Explicit
Sub Multi_Keys_Multi_Items()
    Dim t As Double: t = Timer
    Dim rng As Range, R As Range, txt As String
    Dim i As Long, j As Long, n As Long, ar
    
    Dim ws1 As Worksheet, ws2 As Worksheet
    Set ws1 = Worksheets("arrayInput")      '<~~~ Check names of source & destination sheets carefully
    Set ws2 = Worksheets("arrayAdjustments")
    
    Set rng = ws1.Range("A1:A" & ws1.Cells(Rows.Count, "A").End(xlUp).Row)
    ar = ws1.Range("A1").CurrentRegion
    
    With CreateObject("scripting.dictionary")
        For Each R In rng
            txt = R.Value2 & "|" & R.Offset(0, 1).Value
            If Not .exists(txt) Then
                n = n + 1
                .Add txt, n
                For j = 1 To UBound(ar, 2)
                    ar(n, j) = R.Offset(, j - 1)
                Next j
            Else
                For i = 3 To UBound(ar, 2)
                    ar(.Item(txt), i) = ar(.Item(txt), i) + R.Offset(, i - 1)
                Next i
            End If
        Next R
    End With
    ws2.Range("A1").CurrentRegion.Offset(1).ClearContents
    ws2.Range("A1").Resize(n, UBound(ar, 2)) = ar
    MsgBox "adjSheetFill_fast - end : " & Timer - t & " seconds."
End Sub

Hi Kevin, thank you for posting your code. I will try it today :)

Thanks you for that (y) Looking back at my post, I think I should have explained a bit better how the code actually works. As you probably gathered, it uses a Dictionary approach rather than arrays (dictionaries are brilliant for ultra fast sumifs etc.). As a test, put all your data in your arrayInput sheet on one sheet, and have a second sheet in the same workbook (completely blank) called arrayAdjustments. I tested it on 3K rows and it completed in under 0.5 seconds. I have made a couple of improvements to the code I posted earlier, if you'd like to try this instead?

VBA Code:
Option Explicit
Sub Multi_Keys_Multi_Items_V2()
    Dim t As Double: t = Timer
    Dim rng As Range, R As Range, txt As String
    Dim i As Long, j As Long, n As Long, ar
    
    Dim ws1 As Worksheet, ws2 As Worksheet
    Set ws1 = Worksheets("arrayInput")      '<~~~ Check names of source & destination sheets carefully
    Set ws2 = Worksheets("arrayAdjustments")
    
    Set rng = ws1.Range("A1:A" & ws1.Cells(Rows.Count, "A").End(xlUp).Row)
    ar = ws1.Range("A1").CurrentRegion
    
    With CreateObject("scripting.dictionary")
        For Each R In rng
            txt = R.Value2 & "|" & R.Offset(0, 1).Value
            If Not .exists(txt) Then
                n = n + 1
                .Add txt, n
                For j = 1 To UBound(ar, 2)
                    ar(n, j) = R.Offset(, j - 1)
                Next j
            Else
                For i = 3 To UBound(ar, 2)
                    ar(.Item(txt), i) = ar(.Item(txt), i) + R.Offset(, i - 1)
                Next i
            End If
        Next R
    End With
    ws2.Range("A1").CurrentRegion.Offset(1).ClearContents
    ws2.Range("A1").Resize(n, UBound(ar, 2)) = ar
    
    With ws2.Range(ws2.Cells(2, 3), ws2.Cells(Cells.Find("*", , xlFormulas, , 1, 2).Row, ws2.Cells(1, Columns.Count).End(xlToLeft).Column))
        .Replace 0, "", 1
    End With
    
    For i = 3 To ws2.Cells(1, Columns.Count).End(xlToLeft).Column
        ws2.Cells(1, i) = "Sum of " & ws2.Cells(1, i)
    Next i
    ws2.UsedRange.EntireColumn.AutoFit
    MsgBox "adjSheetFill_fast - end : " & Timer - t & " seconds."
End Sub

Solution
I managed to get it partially going and it looks very promising <2s for 13k rows! Thank you :). What I'm maybe missing or do not understand is the content or "ar" tail rows.
"ar" is initially declared as whole content of "arrayInut" ~13k rows, then code is looping through looking for unique key, if its there then it effectively overwriting given row of "ar" with what it found. If its not unique it will sumup all the data and put it in again in given row of "ar", this is clear. But if we will find only 500 unique keys (txt), wont it overwrite only first 500 rows and we are still left with 12.5k tail rows in the same array?

I'm not following you 100%. The array 'ar' is put into the second sheet ("arrayAdjustments" or "ws2" in my code) after that second sheet is cleared of all its data first. The data in the first sheet ("arrayInput" or "ws1" in my code) shouldn't be affected at all. Is this not quite what you were after?

This is exactly what we are after, yes.

By using this piece, we are putting whole arrayInput sheet, in my case all 13k rows into array "ar".

VBA Code:
    Set ws1 = Worksheets("arrayInput")      '<~~~ Check names of source & destination sheets carefully
    Set rng = ws1.Range("A1:A" & ws1.Cells(Rows.Count, "A").End(xlUp).Row)
    ar = ws1.Range("A1").CurrentRegion

Then we proceed to overwrite some of ar values, based on dictionary entries:

VBA Code:
 If Not .exists(txt) Then
                n = n + 1
                .Add txt, n
                For j = 1 To UBound(ar, 2)
                    ar(n, j) = R.Offset(, j - 1)
                Next j
            Else
                For i = 3 To UBound(ar, 2)
                    ar(.Item(txt), i) = ar(.Item(txt), i) + R.Offset(, i - 1)
                Next i
            End If

But n will never reach 13k, as there is a lot of duplicated entries. Product & key figure combination in arrayInput is not unique. We overwrite only n amount of rows in "ar" and are left with 13k - n that originally came from the 1st code snippet. I'm trying to understand if this is the case, or im missing smth in process.
If this is truly the case then solution is quite easy - cutting rows from ar / putting data in other array

Then we proceed to overwrite some of ar values, based on dictionary entries:
Not quite, you don't actually "overwrite" any values - you use the array "ar" to build the Dictionary based on unique entries only.
We overwrite only n amount of rows in "ar" and are left with 13k - n that originally came from the 1st code snippet. I'm trying to understand if this is the case, or im missing smth in process.
Again, you don't actually "overwrite" anything. If the product+key combination have already been added to the dictionary, then the values are added to what already exists against that product-key combination - effectively doing a Sumifs(). You're not actually left with "13k - n" as you put it, you're left with n.
If this is truly the case then solution is quite easy - cutting rows from ar / putting data in other array
Don't follow this bit. Is this a question, or a proposed "solution" to a problem? If so, what is the problem? Or am I just getting tired (been a long day :sleep:)

Thank you for all the help, please get some rest :) As I though, I'm misunderstanding what the code is doing, but I will get there.
You help me tremendously, once again - thank you!
