Hi Nagarajan,
Thanks for your answer, its working perfectly.
But i want to use this for one item only, So Help with in the query where i have to declare for specific item (Item code "F000012") In below query
SELECT CASE WHEN $[$38.14.number] * $[$38.11.number] <15 Then 15
ELSE $[$38.14.number] * $[$38.11.number] END
