Remove duplicate rows in t-sql query results - sql

Question

I have a some T-SQL below and i am facing a problem where each row is being returned twice with the same values. How can ensure each is returned once or force a select Distinct
;WITH CTE_ReportDetails
AS (
SELECT
CASE(GROUPING(M.Acronym))
WHEN 0 THEN [Acronym]
WHEN 1 THEN 'GRAND TOTAL'
END AS [Company],
CASE(GROUPING(DC.Name))
WHEN 0 THEN DC.[Name]
WHEN 1 THEN 'N/A'
END AS [CatName],
CASE(GROUPING(D.[Name]))
WHEN 0 THEN D.[Name]
WHEN 1 THEN 'Total '+ '('+DC.[Name]+')'
END AS [Name],
SUM(ISNULL(B.One, 0)) AS One,
SUM(ISNULL(B.Two, 0)) AS Two,
SUM(ISNULL(B.Three, 0)) AS Three,
ISNULL(B.Description, '') AS Description,
GROUPING(M.Acronym) AS CompanyGrouping,
GROUPING(DC.[Name]) AS DCatGroup,
GROUPING(D.[Name]) AS DGroup
FROM Dee D
INNER JOIN DeeCategory DC ON D.DeeCategoryId = DC.DeeCategoryId
INNER JOIN BD B ON B.DeeId = D.DeeId
INNER JOIN Report R ON R.RptId = B.RptId
INNER JOIN Company M ON R.CompanyId = M.CompanyId
WHERE (R.ReportDate >= #StartDate AND R.ReportDate <= #EndDate) AND (R.CompanyId IN (SELECT DATA FROM SPLIT(#CompanyIds,',')))
GROUP BY M.Acronym, DC.Name, D.Name,B.Description
WITH ROLLUP
)
SELECT Company, Name As [Dee],
One,
Three,
Two,
(One + Three + Two) AS Total,
Description
FROM CTE_ReportDetails

Your report should have a unique combinations of values from the group by. So, these four columns should be unique:
GROUP BY M.Acronym, DC.Name, D.Name,B.Description
If I had to guess, you are getting duplicates because B.Description is duplicated in the B table. I would suggest removing it from the GROUP BY and changing this line:
ISNULL(B.Description, '') AS Description,
to
ISNULL(max(B.Description), '') AS Description,
