variable "read mode setting" Only Values for InfoProvider

Hi,

I have a problem with Selection Variable for a BEx Query:

- I'm working with SAP BI 7.0 support package 15

- My query is an input ready query;

- Characteristic, I want to filter with variable, has query property Advanced->Query Execution for Filter Value Selection = Only Values in InfoProvider

My problem is:

when I execute a query,

the Select Values for Variables screen appears

I push on the Select from List button

and Select Values For MyCharacteristic appears...

but it shows me all values in master data table of my characteristic instead of only values in the infoprovider!!!

Could someone explain me why it doesn't work correctly?

Thank in advanced
