# Tough excel math formula

This should be simple, but it’s driving me nuts…

I have a spreadsheet that looks like this:

Part Number      Lot Number      Quantity
020-044      Goods      8
020-044      CAH217      -5
020-044      VEG076      1
020-044 Total      4
020-045      Goods      6
020-045      CNS015      -4
020-045      SPG015      -1
020-045      CAH217      -1
020-045      VEG076      1
020-045 Total      1
020-056      Goods      16
020-056      FLX017      -4
020-056      CAS037      -6
020-056      LAS006      -3
020-056      FLP476      -1
020-056 Total      2

What I need is a formula that will go through the spread sheet and copy the total of each part number to the cel next to the “goods” line for each entry. For instance, part #020-044 has a total of 4 units. I simply need that “4” copied to cel D2. The end result should look like this:

Part Number      Lot Number      Quantity      Total
020-044      Goods      8      4
020-044      CAH217      -5
020-044      VEG076      1
020-044 Total            4
020-045      Goods      6      1
020-045      CNS015      -4
020-045      SPG015      -1
020-045      CAH217      -1
020-045      VEG076      1
020-045 Total      1      2
020-056      Goods      16
020-056      FLX017      -4
020-056      CAS037      -6
020-056      LAS006      -3
020-056      FLP476      -1
020-056 Total      2

There are over 50,000 part numbers on this spreadsheet. Some have one or two lot numbers; some have over a dozen, so doing this manually is not an option. I am using MS Excel 2010.

Well:

1.  The format of your file is different than what you originally suggested (re: the Word TOTAL is not in column B)
2.  The range is limited to only the first 17 rows in column C.

Let's open that up and correct for format (now not counting BLANK rows in column B which seems to align with the Total lines).

Attached has this corrected in column C

Hi,

You can use a Macro to do that, in you excel spreadshee, add a module in the visual Basic Editor and copy the macro attached, then assign a Shortcut to the macro and run it, it would what you want and will give you a message when finish.

Hope that helps
``````Sub CopyTotal()

Dim lngLastRow As Long
Dim lngRow As Long
Dim lngCopyToCell As Long
Dim objRange As Range
Dim strPartNumber As String

'Search for any entry, by searching backwards by Rows.
lngLastRow = Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

'Get the Range
Set objRange = ActiveSheet.Range("A2:A" & CStr(lngLastRow))

'Copy the Totals
strPartNumber = ""
lngCopyToCell = 2
For lngRow = 1 To lngLastRow
'If found the Total copy to
If strPartNumber <> Trim(objRange(lngRow, 1).Value) Then
If strPartNumber <> "" Then
objRange(lngCopyToCell, 4).Value = objRange(lngRow - 1, 3).Value
End If
strPartNumber = Trim(objRange(lngRow, 1).Value)
lngCopyToCell = lngRow
End If
Next

MsgBox "Totals Copied."

End Sub

Here, you can do this with a simple SUMIFS formula:  Put this in column D, on the Goods line and see:

=SUMIFS(\$C\$2:\$C\$17,\$A\$2:\$A\$17,\$A2,\$B\$2:\$B\$17,"<>Total")

See attached.

This is a bit better - so paste the formula and copy down...

=IF(B2="Goods",SUMIFS(\$C\$2:\$C\$17,\$A\$2:\$A\$17,\$A2,\$B\$2:\$B\$17,"<>Total"),"")

see attached,

Not for points.

This goes in cell D2.

=SUMPRODUCT((\$A\$2:\$A\$17=A2)*(\$B\$2:\$B\$17="Total")*(C2:C17))

This in D6

=SUMPRODUCT((\$A\$2:\$A\$17=A6)*(\$B\$2:\$B\$17="Total")*(\$C\$2:\$C\$17))

and this in D12

=SUMPRODUCT((\$A\$2:\$A\$17=A12)*(\$B\$2:\$B\$17="Total")*(\$C\$2:\$C\$17))

Sorry, maybe I wasn’t too clear…

1.      I do not want to re-calculate anything. The totals are already calculated. I simply need to copy the total from one cel to another.
2.      There are thousands of part numbers, each with up to 20 lot numbers. It is not feasible to paste a formula for each part number manually.

You only need to copy and paste once.  for all your thousands of part numbers.  I've done this with > 100,000 items before and no issues.

The formula works for an infinite variety of part numbers...  here, this is more generic:

=IF(B2="Goods",SUMIFS(\$C:\$C,\$A:\$A,\$A,\$B:\$B,"<>Total"),"")

Now you copy that down for as much data as you have - and if its the entire set of rows it will work.  For several thousand, its not intensive...

Otherwise, the macro is your solution and maintaining it should be the only concern...

PS - You copy this formula down (not individually for each part number)

:)

Cheers,

....that still involves re-summing a total that already exists......

This version will just lookup the next Total row and give you the relevant number

=IF(B2="Goods",VLOOKUP(D\$1,B3:C\$50000,2,0),"")

Place that formula in D2 and copy down

Incorrect.  The formula I provided does not resum any totals.

Ah - I see what you mean by re-summing, in that it just needs to be looked up.  I responded too quickly :)

Nice and tight, barry.

I appreciate the help, but I think I’m missing something here… I’ve tried each formula, but it seems to die after the first few entries. I attached the entire spreadsheet and yes, I’ve tried with and without the subtotals… also, keep in mind that the other column on the spreadsheet need to stay there…

See Dave, I told you I was missing something... Turns out it's my mind...

You nailed it! Thanks a bunch!!!
