Hiding Rows Based On Different Column Data Ranges - excel

Question

I am fairly new to using VBA and am trying to create a code that will look at two different columns with varying data ranges and hide rows beyond the last data point (referencing both columns).
At the moment I have this;
Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
'Updateby Extendoffice 20160913
Dim xRg As Range
Application.ScreenUpdating = False
For Each xRg In Range("G24:G71, N24:N71")
If xRg.Value = "" Then
xRg.EntireRow.Hidden = True
Else
xRg.EntireRow.Hidden = False
End If
Next xRg
Application.ScreenUpdating = True
End Sub
Column G and Column N are peoples names in two separate pivot tables. So depending on the day the range of data in each of these columns can differ (the pivot table has different filters). For example today there could be 50 rows of data in Column G and 40 in Column N. In this case the above formula would work and hide rows 51 to 71 with no data in. However, if Column G has 40 rows of data and Column N has 50 rows then it would reference column G and hide rows 41 - 71, hiding unwanted data from column N.
Is there a way to get the code to look at Columns G & N, identify which has a larger data range and hide rows beyond that point.
Thanks in advance for any help.

Try this one:
Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
Dim xRg As Range, xCell As Range, bHide As Boolean
Application.ScreenUpdating = False
For Each xRg In Range("G24:G71, N24:N71").Rows
bHide = True
For Each xCell In xRg.Cells
If IsEmpty(xRg.Value) = False Then
bHide = False
End If
Next xCell
xRg.EntireRow.Hidden = bHide
Next xRg
Application.ScreenUpdating = True
End Sub
Explanation of the error: your code iterates through all cells, and makes a decision based on individual cells. That is incorrect because you want to know if both cells in a row are empty.
Solution: So you should iterate rows in an outer loop, and cells inside the given row in an inner loop. Take note if there is any cell that is non-empty, and make the decision on hiding the row based on this.
Update
Sorry, my code did not work because Range("G24:G71, N24:N71") consists of 2 .Areas, and although .Rows.Count returns 48, For Each enumerates 96 "rows", each consisting of 1 cell (48 rows for each area).
I modified the code to take into account Areas:
Private Sub Worksheet_PivotTableUpdate()
Application.ScreenUpdating = False
With Range("G24:G71,N24:N71")
Dim r As Long: For r = 1 To .Areas(1).Rows.Count
Dim bHide As Boolean: bHide = True
Dim xArea As Range: For Each xArea In .Areas
If IsEmpty(xArea.Cells(r, 1).Value) = False Then
bHide = False
End If
Next xArea
.Rows(r).EntireRow.Hidden = bHide
Next r
End With
Application.ScreenUpdating = True
End Sub

This is another way to loop pivot table. The below code loop in two different columns (Items & Quantity) and hidden rows:
Option Explicit
Sub Hide()
Dim pvtTable As PivotTable
Dim pvtItem As PivotItem
Dim pvtRow As Long
'Set table with name
Set pvtTable = ThisWorkbook.Worksheets("Sheet1").PivotTables("PivotTable1")
'Loop Items in a specific field
For Each pvtItem In pvtTable.PivotFields("Item").PivotItems
'Check conditions
pvtRow = pvtRow + 1
If pvtItem.Value = "A" Then
pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = True
ElseIf pvtItem.Value <> "A" And pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = True Then
pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = False
End If
Next pvtItem
'Loop Items in a specific field
For Each pvtItem In pvtTable.PivotFields("Quantity").PivotItems
'Check conditions
pvtRow = pvtRow + 1
If pvtItem.Value = "A" Then
pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = True
ElseIf pvtItem.Value <> "A" And pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = True Then
pvtTable.DataBodyRange.Rows(pvtRow).EntireRow.Hidden = False
End If
Next pvtItem
End Sub
