Planning filters in SAP IBP, created via the Manage Planning Filters app (Fiori-based), define subsets of data (e.g., by Product, Location) for use across various applications. Their applicability depends on SAP IBP’s functional scope.

Option A: Planning view templates in the SAP IBP, add-in for Microsoft ExcelThis is correct. Planning filters can be applied to planning view templates in the Excel add-in to restrict data displayed or edited (e.g., show only products in Region X). This is a core feature for planners, as per SAP IBP’s Excel integration documentation.

Option B: Jobs in the Application Jobs appThis is correct. Planning filters can be parameters in application jobs (e.g., Copy Operator, Purge Data) to limit the scope of data processed (e.g., purge data for specific Locations). This is a standard capability in the Application Jobs app, per SAP IBP’s job management guides.

Option C: Compare function in the Planning Areas appThis is incorrect. The Planning Areas app manages planning area configurations, and while it has a "Compare" function to analyze differences, planning filters are not applied here. Filters are for runtime data, not configuration comparison.

Option D: Supply chain graph in Supply Chain Network appThis is incorrect. The Supply Chain Network app visualizes the network (e.g., Locations, Transportation Lanes), but planning filters are not directly applied to this graph. Filters affect data views, not network visualizations.

Thus, A and B are the correct objects where planning filters can be applied, per SAP IBP’s official functionality.
