"No Values to Display" in Query Filter

Hi All,

I'm using BEX Query to generate WEBI Report. In Query Filters, I have draged an Object to filter an value, but in "Value(s) from the List" Option I couldnt see any values from the source systerm by entering search pattern "*" instead it displays "No values to display". In Source System this object has values.

Please guide me to proceed further.

With Regards,

Raji. S
