QUESTION: Bob;

you've helped me before, which i am so grateful for!

Hope you can help me again. I have a spreadsheet with 3 columns

Col A - operator ID, Col B - claim number and Col C - date.

The sheet is sorted in Operator ID order. I need a routine - Macro, preferably, which would randomly select 3 claims for each operator (non-repeating) and if possible, create a new worksheet of this random selection. So i will end up with 3 random records for each operator (consisting of all 3 columns, A,B,C).

your help is ALWAYS much appreciated!

George.

ANSWER: Sub ThreeOfEach()

Set curr = ActiveSheet

Set sel = Selection

Range("D1:E1").Value = 0

Range("D2:D" & Range("A65000").End(xlUp).Row) = [row(1:65000)]

Range("E2:E" & Range("A65000").End(xlUp).Row).FormulaR1C1 = "=rc1&rand()"

[a1].CurrentRegion.Sort key1:=[e2], order1:=xlAscending

Worksheets.Add

Set nw = ActiveSheet

curr.Range("A1:C4").Copy Range("A1")

i = 2

Do

n = curr.Columns(1).Find(curr.Cells(i, 1).Value, searchdirection:=xlPrevious).Row

n = n + 1

If curr.Cells(n, 1).Value = "" Then GoTo es

curr.Cells(n, 1).Resize(3, 3).Copy Cells(Range("A60000").End(xlUp).Row + 1, 1)

i = n

Loop

es:

curr.Activate

[a1].CurrentRegion.Sort key1:=[d2], order1:=xlAscending

Range("D:E").Delete

nw.Activate

Columns.AutoFit

End Sub

QUESTION: Bob;

this is the macro you gave me in January and it works great and we are using it every week. Now, is there a way to modify the macro to instead of selecting 3 random claims for each operator; to select a set percentage of random claims for each operator: e.g.: 20% of random claims for each operator. Your help is greatly appreciated!!!

George.

Sub APercentOfEach()

Dim arr()

Dim arrcount As Integer

Set curr = ActiveSheet

Set sel = Selection

pct = Application.InputBox("What percent?", Type:=1)

If pct > 100 Or pct = 0 Then

MsgBox "Enter a value between 1 and 100"

Exit Sub

End If

Range("D1:E1").Value = 0

Range("D2:D" & Range("A65000").End(xlUp).Row) = [row(1:65000)]

Range("E2:E" & Range("A65000").End(xlUp).Row).FormulaR1C1 = "=rc1&rand()"

Range("F2:F" & Range("A65000").End(xlUp).Row).FormulaR1C1 = "=INT(" & pct / 100 & "*COUNTIF(c1,rc1))"

[a1].CurrentRegion.Sort key1:=[e2], order1:=xlAscending

num = [f2].Value

[g2].FormulaArray = "=match(true,offset(A2,1,0,1000,1)<>A2,0)"

nx = [g2].Value

[g2].Copy

Set g = [g2]

ReDim Preserve arr(1)

arr(1) = 2

arrcount = 1

Do

Set g = g.Offset(nx)

arrcount = arrcount + 1

ReDim Preserve arr(arrcount)

arr(arrcount) = g.Row

g.PasteSpecial

If Application.IsNA(g) Then Exit Do

nx = g.Value

g.Copy

Loop

Worksheets.Add

Set nw = ActiveSheet

For i = 1 To arrcount - 1

numtocopy = curr.Cells(arr(i), 6).Value

If i = 1 Then numtocopy = numtocopy + 1

curr.Cells(IIf(i = 1, 1, arr(i)), 1).Resize(numtocopy, 3).Copy Range("A60000").End(xlUp).Offset(1)

Next

Rows(1).Delete

[d1].Value = pct & "% of operators represented."

es:

curr.Activate

[a1].CurrentRegion.Sort key1:=[d2], order1:=xlAscending

Range("D:G").Delete

nw.Activate

Columns.AutoFit

End Sub
