Restricted measure for HANA data sources in AO2.1

Dear All,

I tried to follow guide to add a restricted measure (Restriction) for HANA data source, but did not make it work.

http://help.sap.com/businessobject/product_guides/AMS21/en/21_1_analysisplugin_user_en.pdf

Guide p.140 says:

1. Select a measure heading or a data cell in the crosstab.

2. Choose Calculations -> Add Restriction... .

However, with my HANA http connection in AO2.1, "Add Restriction" is grayed out when I selected a measure heading and "Calculation" in Ribbon is greyed out when I selected a data cell.

Please give me some advice.
