    SELECT DISTINCT
Name,
Desc as Description,
Category,
Usage,
No_of_Pages,
Author,
Confidential
FROM Docsdb.dbo.tblProperty
WHERE
   (CASE 
       WHEN '" & Confidential_Flag &"'='1' AND Confidential='1' THEN 1
       WHEN '" & Confidential_Flag &"='0' AND Confidential='0' THEN 0
    )
    AND ('" & Doc_Name &"' = '' OR Name     = '" &Doc_Name &"')
    AND ('" & Doc_Desc &"' = '' OR Desc     = '" &Doc_Desc &"')
    AND ('" & Category &"' = '' OR Category = '" &Category&"')
    AND ('" & Usage    &"' = '' OR Usage    = '" &Usage&"')

    You were wrapping the catergories in '' so blanks would of always been empty strings. Try the above

Hi shavish ,

Thank you for the update. It's encouraging to know your query works in SQL. However, Power BI may handle parameter filtering differently. The solution provided by johnbasha33 , ensures that when parameters are not selected, all records are displayed rather than filtered out. Please try this fix in Power BI and inform us if you encounter any issues.

Thank you for your responses johnbasha33 & Deku .
