Simple way to refresh power pivot from VBA in Excel 2010? - vba

Question

I want to perform the equivalent actions of:
Power Pivot > Tables > Update All
Pivot Table Tools > Data > Refresh All
using VBA. All the tables are Excel tables contained within the file.
Is there a simple way to do this in Excel 2010?

Answer 1

For Pivot Tables update, this code will work smoothly :
ThisWorkbook.RefreshAll
Or, if your Excel version is too old :
Dim Sheet as WorkSheet, _
Pivot as PivotTable
For Each Sheet in ThisWorkbook.WorkSheets
For Each Pivot in Sheet.PivotTables
Pivot.RefreshTable
Pivot.Update
Next Sheet
Next Pivot
In Excel 2013, to refresh PowerPivot, it is a simple line ActiveWorkbook.Model.Refresh.
In Excel 2010, ... It is FAR more complicated! Here is the general code made by Tom Gleeson :
