SAP has introduced a way to set the User Option in EPM add-in for SAP BPC 10. Here is a little write up about how you can set up the “user options” while developing EPM Add-in reports using SAP BPC 10.
While deploying a report, sometimes you want to force a Refresh when the context is changed. Earlier, the users could activate this option manually. In other words, this option is enabled or disabled by the user, the implementation team had little control* over this.
The process of setting up the options manually by the users.
User Options >> Automatic Refresh on Context Changes

The solution of this is to create a simple API based VBA code to set this option. This document will guide you to set-up this option as part of the work book open event. This will make sure that every time the user opens the work book this AutoRefresh is set.
Step 1: Open the Visual Basic Development Window (shortcut ALT + F11)
Step 2: Add reference to the FPMXLClient

Step 3: Add a new module (this works as a place holder of your methods, functions and variables)
Step 4: Add the following code.
Function AFTER_WORKBOOK_OPEN()
Dim EPMObj As New FPMXLClient.EPMAddInAutomation
EPMObj.SetUserOption "AutomaticRefresh", True
End Function

Step 5: Save the work book as the macro enabled work book or template. The macro will not be saved if this step is not followed.
