I have a bank of data that is updated monthly. I need to analyze said data to determine first all values below
64, then I need to look for two consecutive instances of this event. Once found, I would like a value returned to indicate this vendor is a problem.
The second piece of the puzzle is that I also need to analyze the data for three consecutive instance of values above
64 if the vendor has been labeled as problem.
I am not sure if VBA is appropriate or a formula approach will work. I am able to write most VBA code and work with basic formula. Example here:
This code assumes your data starts in cell B4 (such as your picture suggests) and outputs a problem if under 64 is found twice in a row. However, if above 64 is found 3 times in a row AFTER the issue, it returns “N” for no problem:
Sub VendorProblems() Dim cl As Long, LastRow As Long, i As Long, LastCL As Long, Problem As String LastRow = ActiveSheet.Range("A" & Rows.Count).End(xlUp).Row LastCL = ActiveSheet.Cells(4, Columns.Count).End(xlToLeft).Column - 1 For i = 4 To LastRow Problem = "" For cl = 2 To LastCL Set r1 = Cells(i, cl) Set r2 = r1.Offset(0, 1) Set r3 = r1.Offset(0, 2) If r1.Value < 64 And r2.Value < 64 Then Problem = "Y" Else End If If r1.Value >= 64 And r2.Value >= 64 And r3.Value >= 64 Then Problem = "N" Else End If Next cl If Problem = "Y" Then Cells(i, LastCL + 1).Value = "Y" Else Cells(i, LastCL + 1).Value = "N" End If Next i End Sub
Here is the simplest solution pasting these formulas in a single column. If the first formula column is False, you can just ignore the second.
Two consecutive values below 64:
=OR( A1 + B1 < 128 , B1 + C1 < 128, etc.)
Three consecutive values above 64:
=OR( A1 + B1 + C1 > 192 , B1 + C1 + D1 > 192 , etc.)
