The PivotGrid widget is designed to perform different DISCOVER requests in order to get the relevant metadata (dimension labels and etc). For instance, in the "Include fields" case the widget will perform a MDSCHEMA_MEMBERS request with LEVEL_UNIQUE_NAME param
to get the dimension root member. On expand it will call MDSCHEMA_MEMBERS with MEMBER_UNIQUE_NAME param.
If you would like to restrict the displayed filter data, then you will need to restrict the DISCOVER requests. The widget will call the parameterMap
callback with a second argument "discover". You can use that function to send additional authorization params
. The other option is to restrict the DISCOVER requests on server side based on the user identity.
