Need to create an RDLC report for dynamic column result of this dynamic query

I have created a PIVOT query, It returns absolute values. Please look at it once and suggest me what I need to do further on it.

USE [BSJ_APPLN]
GO/****** Object:  StoredProcedure [dbo].[Project_To_Ship_All_Location]    Script Date: 05/27/2017 11:57:58 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO--=============================================--Author:<Author,,Name>--Create date:<CreateDate,,>--Description:<Description,,>--=============================================
ALTER PROCEDURE [dbo].[Project_To_Ship_All_Location]--Add the parameters for the stored procedure here@FromDate date,@ToDate date
ASBEGIN-- SET NOCOUNT ON added to prevent extra result sets from-- interfering with SELECT statements.
     SET NOCOUNT ON;
     DECLARE @cols AS NVARCHAR(MAX),@query  AS NVARCHAR(MAX)select@cols= STUFF((SELECT distinct ','+ QUOTENAME(ItemNumber)from PJ_Item_M
            FOR XML PATH(''), TYPE).value('.','NVARCHAR(MAX)'),1,1,'')set@query='select * from
(select Store_Number,ItemNumber, SUM(CAST(Tot_PlanToShip as decimal(9,2))) Qty from PJ_Daily_DbnMatrix_T
where
 variation = '''' and Distbn_Date >= '''+Cast(@FromDateas varchar(15))+''' and
  Distbn_Date <= '''+Cast(@ToDateas varchar(15))+''' group by ItemNumber,Store_Number)t PIVOT
(
  MAX(Qty)
  FOR ItemNumber IN('+@cols+')
) AS p;
 '

execute(@query);

Please tell me step by step how to work on Matrix column group or any other option in RDLC to show dynamic data(including column names).

Thanks,

Deepak
