How to Disable PivotTable Fields List for?

[mmanda]

I would like to disable the pivot table field list once I am finished creating pivot tables and charts with the Workbook, So users will not have the ability to add new fields to the Pivot table and charts. At the same time I want users to interact using slicers. Protected Sheet is not working for slicers. I was actually able to disable using macros, but that doesn't work for us as we need to publish those workbooks to SharePoint 2013 and Macros is not supported in SharePoint Browser mode, so they end up seeing the Fields list. I cant use Excel web part in SharePoint as we will have too many files. Are there any other options ? Thanks Manoj Manda
