I'm trying to define in my business model control row-level security, but does not seem to do anything.
To give you an idea, in my business view I have a table with a user field, in the model I have defined a Global Constraint that I initially filtered by a particular user, something like:

[<id_table>. <id_colum>] = "myuser".

I keep my metadata and published it in pentaho. I have a report that pulls the metadata, and displays data including user and returns all rows without filtering by the user that I am indicating.
Does anyone have idea that I may be missing?
My version of the meta data editor and pentaho server is 4.8.
Thanks in advance and best regards.
