How to change F4 custom settings for value restriction tab in Bex query

Hi Gurus,

I have created a hierarchy node filter on 0PLANT and I am using the setting 'Only values in infoprovider'

for the Filter Value Selection at Query execution (at the query level).

When I open the filter to select a plant from the hierarchy I get the values from the master data table.

I am trying to change this behavior in the Value restriction tab of the settings icon in the filter screen, so the hierarchy only shows values in infoprovider.

The problem is that the custom value only allows one option which is pulling data from Master data table. I have checked the settings in the back end at the infoobject level and infoprovider level for Filter Value Selection at Query execution.  The value for the infoobject in the Bex explorer tab is set up as 'Only values in infoprovider'. There is no value selected at the infoprovider level. In any case, the values at the query level should overwrite any underlying setting - in this case they are all consistent. But still, the hierarchy only shows master data values.

Please kindly advice on the above in case you came across any similar situation or if I am missing any setting.

Thanks in advance.

Alex.
