How to implement an advanced look up macro in excel? - excel

Question

How do I have to change the following macro code and formula which works for the data and question below(earlier data/question,column F) to make it suitable for Problemstatement (2) and (3) ?
(1)
Earlier data
Colums C,D,E,F
Row 1 4,10,40,F
Row 2 4,12,48,F
Row 3 4,14,56,F
Row 4 3,16,48,F
Row 5 1,18,18,F
Row 6 1,20,10,F
Row 7 0,22,0,0
Intention of the column F
If Cx <> 0, Fx = Cx
If Cx = 0, Fx = the address of the cell in Column C that produces minimum of (C1 * D7 - E1, C2 * D7 - E2, ..., CN * D7 - EN) and is >0.
** Macro code and formula for column F**
Public Function MinimumC()
Dim rngCurrent As Range
Set rngCurrent = Application.ThisCell
Dim rngMin As Range
Dim minimum As Long
minimum = 100000000
Dim tmp As Long
Dim rngC As Range
Set rngC = ActiveSheet.Range("C1:C" & rngCurrent.Row - 1)
For Each c In rngC.Cells
If c.Value2 <> 0 Then
tmp = c.Value2 * rngCurrent.Offset(0, -2).Value2 - c.Offset(0, 2)
If tmp < minimum Then
minimum = tmp
Set rngMin = c
End If
End If
Next c
MinimumC = rngMin.Value2
End Function
Formula in F1 and copy down column F: =IF(C1<>0,C1,MinimumC())

How do I have to change the macro and formula to archieve the same in the following data format:
New data 1
Colums AZ,BA,BB,BC,BD,BE,BF,BG
Row 1 4,4,4,10,10,10,120,444
Row 2 4,4,4,12,12,12,144,444
Row 3 4,4,4,14,14,14,168,444
Row 4 3,3,3,16,16,16,144,333
Row 5 1,1,1,18,18,18,54,111
Row 6 1,1,1,20,20,20,60,111
Row 7 0,0,0,22,22,22,0,???
Intention of the column BG
If(And(AZ>0;BA>0;BB>0);Concatenate(AZ;BA;BB))
otherwise, the adress cell of Concatenate (AZ;BA;BB), unequal to 000, to minimize the following difference (AZn*BCx+BAn*BDx+BBn*BEx)-BFn

How do I have to change the macro and formula from (1) to archieve the same in the following data format:
New data 2
Colums AZ,BA,BB,BC,BD,BE,BF,BG,BH,BI,BJ,BK,BL,BM,BN
Row 1 4,4,4,10,10,10,120,444,3,3,3,10,10,10,90,333
Row 2 4,4,4,12,12,12,144,444,3,3,3,12,12,12,108,333
Row 3 4,4,4,14,14,14,168,444,3,3,3,14,14,14,126,333
Row 4 3,3,3,16,16,16,144,333,3,3,3,16,16,16,144,333
Row 5 1,1,1,18,18,18,54,111,2,2,2,18,18,18,108,222
Row 6 1,1,1,20,20,20,60,111,1,1,1,20,20,20,60,111
Row 7 0,0,0,22,22,22,0,?,0,0,0,22,22,22,0,?
Intention of the column BN
If(And(AZ>0;BA>0;BB>0;BH>0;BI>0;BJ>0);0
otherwise the adress of the cell either concatenate (AZ;BA;BB) or concatenate (BH;BI;BJ) to minimize (AZn*BCx+BAn*BDx+BBn*BEx)-BFn or (BHn*BKx+BIn*BLx+BJn*BMx)-BNn .In this case i need to find the adress of either concatenate (AZ;BA;BB) or concatenate (BH;BI;BJ) with the min difference and that cell of BN (concatenate) unequal to 000.
I appriciate the help. Thank you very much!!!!

Answer 1

To solve problem 2, the macro is basically identical. You just need to replace the C range with the AZ range, and change the calculation of tmp:
Public Function CalcBG()
Dim rngCurrent As Range
Set rngCurrent = Application.ThisCell
Debug.Print rngCurrent.Address
Dim rngMin As Range
Dim minimum As Long
minimum = 100000000
Dim tmp As Long
Dim rngAZ As Range
Set rngAZ = ActiveSheet.Range("AZ1:AZ" & rngCurrent.Row - 1)
Debug.Print rngAZ.Address
For Each c In rngAZ.Cells
If c.Value2 <> 0 Then
tmp = ((c.Value * rngCurrent.Offset(0, -4).Value2) + (c.Offset(0, 1).Value2 * rngCurrent.Offset(0, -3).Value2) + (c.Offset(0, 2).Value2 * rngCurrent.Offset(0, -2)) - c.Offset(0, 6).Value2) 'This is your calculation (AZn * BCx) + ... - BFn
If tmp < minimum Then
minimum = tmp
Debug.Print minimum
Set rngMin = c.Offset(0, 7)
Debug.Print rngMin
End If
End If
Next c
Debug.Print minimum
Debug.Print rngMin.Address
CalcBG = rngMin.Address 'Return the address rather than the value
End Function
And the formula:
=IF(AND(AZ1>0,BA1>0,BB1>0),CONCATENATE(AZ1,BA1,BB1),CalcBG())
Place that in BG1 and copy down Column BG.
Problem 3
This added a couple more variables, but the basic structure is the same.
Based on the data, I also assumed that "If(And(AZ>0;BA>0;BB>0;BH>0;BI>0;BJ>0);0" should have been If(And(AZ>0;BA>0;BB>0;BH>0;BI>0;BJ>0),concatenate(bh,bi,bj). Otherwise your values in BO would all be 0. Also, your last column is BO, not BN. :)
Here's the macro:
Public Function CalcBO()
Dim rngCurrent As Range
Set rngCurrent = Application.ThisCell
Debug.Print rngCurrent.Address
Dim rngMin As Range
Dim minimum As Long
minimum = 100000000
Dim tmp1 As Long
Dim tmp2 As Long
Dim lowest As Long
Dim rngAZ As Range
Set rngAZ = ActiveSheet.Range("AZ1:AZ" & rngCurrent.Row - 1)
Debug.Print rngAZ.Address
For Each c In rngAZ.Cells
If c.Value2 <> 0 Then
'(AZn*BCx+BAn*BDx+BBn*BEx)-BFn
tmp1 = ((c.Value2 * rngCurrent.Offset(0, -12).Value2) + (c.Offset(0, 1).Value2 * rngCurrent.Offset(0, -13).Value2) + (c.Offset(0, 2).Value2 * rngCurrent.Offset(0, -10).Value2)) - c.Offset(0, 6).Value2
'(BHn*BKx+BIn*BLx+BJn*BMx)-BNn
tmp2 = ((c.Offset(0, 8).Value2 * rngCurrent.Offset(0, -4).Value2) + (c.Offset(0, 9).Value2 * rngCurrent.Offset(0, -3).Value2) + (c.Offset(0, 10).Value2 * rngCurrent.Offset(0, -2).Value2)) - c.Offset(0, 14).Value2
lowest = WorksheetFunction.Min(tmp1, tmp2)
If lowest < minimum Then
minimum = lowest
Debug.Print minimum
Set rngMin = c.Offset(0, 7)
Debug.Print rngMin
End If
End If
Next c
Debug.Print minimum
Debug.Print rngMin.Address
CalcBO = rngMin.Address
End Function
And here is the formula for BO1. Copy down as usual:
=IF(AND(AZ1>0,BA1>0,BB1>0,BH1>0,BI1>0,BJ1>0),CONCATENATE(BH1,BI1,BJ1),CalcBO())
There's a lot of repetition among those macros, and they could probably be condensed. But they should do what you need.
One note: The macros won't differentiate between equal minimum values. For example, in problem set 3, the two calculations (AZn ... - BFn and BHn ... - BNn) return the same value, 6, which also happens to be the minimum value among all the calculations. In this case, it returns the first address (AZn ... - BFn). So in Problem 3, you will get the answer $BG$6 in BO7, even though $BG$6 and $BO$6 both satisfy the conditions. Your requirements didn't specify what to do in case there was more than one minimum value, so I left it as it is.
Let me know if you need any help with the above.
