Opening a EPMContext from an API

Hi All,

I want to trigger the EPMContextMember function from an api, but I cannot find the correct one.

Sub SelectCostCenter()

Dim api As New FPMXLClient.EPMAddInAutomation

api.OpenMemberSelector(api.GetActiveConnection(ActiveSheet), "COSTCENTER", "COSTCENTER_A")

End Sub

This function works, but makes it possible to select multiple values, which is not allowed.

Is there an other api available that is suited?

Regards,

Vincent
