running multiple macros when cells in a range are changed - vba

Question

bear with me, as I am a complete vba newbie and wrapping my head around what I already have has already taken me much longer than I care to admit.
I have a workbook with one master list "ITEMS" and several (up to 15) sub-tabs that grab information from the ITEMS sheet. I've been able to make this happen using buttons on each sub sheet which call this code:
Private Sub getNELL_Click()
Sheets("ITEMS").Range("A1:K400").AdvancedFilter Action:=xlFilterCopy, _
CriteriaRange:=Sheets("ITEMS").Range("O1:O2"), CopyToRange:=Range("A1:K1") _
, Unique:=False
End Sub
This code successfully grabs each relevant row into the sheet each time I click the button, where each getX has a different name/criteria range (getRILEY, getELLE etc.)
But what I'm looking to do next is to have these macros run automatically when any cell in the G column of the ITEMS sheet is changed. In plain text, what I need is:
When [Any Cell in Column G] in Sheet("ITEMS") is changed
Run getNELL, getRiley, getELLE (x15 different macros)
here's my file with all the sheet (sic) in it.
EDIT:
and it's done!
moving the macros to a module instead of in each individual sheet, making them public and removing the _Click, along with the following code worked the magic I needed.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim KeyCells As Range
Set KeyCells = Range("G2:G400")
If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then
getNELL
getMIKA
getRILEY
getJANNA
getWOO
getELLE
getMK
getLAURA
getFLIPSE
getJENN
getCRIS
End If
End Sub

Answer 1

First off, use this link as a resource for triggering an event when cells change. That's usually just in the subroutine declaration.
For the code, change all of your private subs to public subs by replacing "private" with "public". Then in your subroutine list the subroutines to call:
>
Subx
Suby
Subz
end sub
Sorry the answer isn't super detailed as I am typing from my phone. Also, those sub examples should each be on their own line. I can't seem to change that on here.

Answer 2

you have already created filter criteria in ITEM sheet (grey highlighted)
so create one mapping for what sheet needs what criteria range in INDEX sheet
e.g.
SheetName Criteria Mapping
nell O1:O2
mika P1:P2
riley Q1:Q2
janna R1:R2
woo S1:S2
elle O3:O4
mk P3:P4
laura Q3:Q4
flipse R3:R4
jenn S3:S4
cris O5:O6
Add this code in a Module
Public Sub pGet_Data(ByVal SheetName As Worksheet, ByVal CriteriaRng As Range)
ThisWorkbook.Worksheets("ITEMS").Range("A1:K400").AdvancedFilter _
Action:=xlFilterCopy, _
CriteriaRange:=CriteriaRng, _
CopyToRange:=SheetName.Range("A1:K1"), _
Unique:=False
End Sub
And in Thisworkbook Module add given code:
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim rngCriteriaRange As Range
Dim rngOneMap As Range
Dim wksSheet As Worksheet
If Sh.Name = "ITEMS" And Target.Column = 7 Then
Set rngCriteriaRange = Sh.Range("W6:X16") '<--you can make it dynamic
For Each rngOneMap In rngCriteriaRange.Rows
Set wksSheet = ThisWorkbook.Worksheets(rngOneMap.Cells(1, 1).Value)
Application.StatusBar = "Updating [" & wksSheet & "] Sheet"
Call pGet_Data(wksSheet, wksSheet.Range(rngOneMap.Cells(1, 2).Value))
Next rngOneMap
End If
MsgBox "Sheets has been updated.", vbOKOnly, "Be Happy..."
ClearMemory:
Set rngCriteriaRange = Nothing
Set rngOneMap = Nothing
Set wksSheet = Nothing
End Sub
I think this will resolve what you are looking for... :)
