SQL SUM JOIN问题

Question

我再次来找你寻求进一步的帮助:)我已经达到了这样的程度，我可以加入两个查询，生成具有不同值的重复列，但是我仍然面临整个查询产生许多每个大小的结果（文字和技术是1：1）我怎样才能生成一个只为每个大小显示一次每种材料的查询？在此先感谢并感谢您的所有帮助：

SELECT * 
FROM


(SELECT         P.PLANT_CODE,
                P.STOCK_CATEGORY,
                P.MATERIAL,
                P.DISTRIBUTION_VERSION_CODE,
                P.PERIOD_CODE,
                P.REQUIREMENTS_DATE,
                P.PLANNED_QTY AS 'REM PLAN QTY',
                P.VERSION_IND_FLAG,
                P.SIZE_LITERAL,
                P.WITHDRAWN_QUANTITY,
                P.TECHNICAL_INDEX,
                P.PLANNED_QTY + P.WITHDRAWN_QUANTITY AS 'ORIGINAL FCST QTY'
 FROM           VW_PLANNED_REQMNTS_TXT P
 WHERE          P.PLANT_CODE IN ('6040','6041')
 AND            P.STOCK_CATEGORY IN ('A60385000','A60385003')
 AND            P.DISTRIBUTION_VERSION_CODE IN ('00','01','ZU','Z2')
 AND            P.REQUIREMENTS_DATE < GETDATE() - 59
 AND            P.PLANNED_QTY > 0) AS P1

 JOIN      

 (SELECT
                SUM(P.PLANNED_QTY) AS 'FUTURE_FCST',
                P.MATERIAL,
                P.TECHNICAL_INDEX,
                P.SIZE_LITERAL
 FROM           VW_PLANNED_REQMNTS_TXT P
 WHERE          P.REQUIREMENTS_DATE > GETDATE()
 AND            P.PLANNED_QTY > 0
 GROUP BY       P.PLANNED_QTY,
                P.MATERIAL,
                P.TECHNICAL_INDEX,
                P.SIZE_LITERAL) AS P2

 ON             P1.MATERIAL = P2.MATERIAL
 AND            P1.TECHNICAL_INDEX = P2.TECHNICAL_INDEX`

 ORDER BY       P1.MATERIAL,
                P1.TECHNICAL_INDEX;
