Hi there

you need to use pragma restrict references to call a function from the sql query. Define the pragma at the package header

PRAGMA RESTRICT_REFERENCES (get_concat_description, WNDS, WNPS );

get_concat_description is the function name and you should define the above line in the package header

Hope it helps

Good Luck
