how to accomplish this?

问题

having below data

with below format

CREATE TABLE [dbo].[Sample](
    [CCMPNY] [varchar](2) NOT NULL,
    [CCUST#] [numeric](7, 0) NOT NULL,
    [RDDYSR] [varchar](7) NOT NULL,
    [CBLNAM] [varchar](30) NOT NULL,
    [CCYCLE] [varchar](2) NOT NULL,
    [RDSIZE] [varchar](2) NOT NULL,
    [RDCHGC] [varchar](2) NOT NULL,
    [RDDAY] [numeric](1, 0) NOT NULL,
    [RDROUT] [varchar](4) NOT NULL,
    [RDQTY] [numeric](5, 0) NOT NULL

how can I get below layout

Columns Marked in red

FREQ: "Count" of Days in "RDDYSR" field
LIFTS: "Lifts" = "RDQTY" times "Freq"
VOLUME: "Volume" = "RDQTY" times "RDSIZE" times "Freq"

Week Days columns: 
MON: If "RDDYSR" includes "M", "RDQTY" times "RDSIZE", else "blank".  
TUE: If "RDDYSR" includes "T", "RDQTY" times "RDSIZE", else "blank", etc.

Notes

that each "CCUST" generates only one data line unless 
(1) there are multiple "RDCHGC" values (CCUST 43), 
(2) there are multiple "RDSIZE" values (CCUST 10723); or, 
(3) there are multiple "FREQ" values (no example).

Thanks for your help.

This should give you what you're looking for a little bit simply. I'm not sure what your identifier for Sunday is so I've commented this out with --

select CCUST# CCUST, CBLNAM,RDCHGC, RDQTY, RDSIZE, Len(Replace(RDDYSR, '-', '')) FREQ, 
RDQTY * Len(Replace(RDDYSR, '-', '')) LIFTS, 
RDQTY * Cast(RDSIZE as int) * Len(Replace(RDDYSR, '-', '')) Volume, RDDYSR,
Case when CHARINDEX('M', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Mon,
Case when CHARINDEX('T', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Tue,
Case when CHARINDEX('W', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Wed,
Case when CHARINDEX('H', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Thu,
Case when CHARINDEX('F', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Fri,
Case when CHARINDEX('S', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Sat
--,Case when CHARINDEX(RDDYSR, 'X') > 0 then RDQTY * Cast(RDSIZE as int) end as Sun   --Whatever Sunday identifier is

from Sample

Group by CCUST#, CBLNAM, RDCHGC, RDQTY, RDSIZE, RDDYSR

Try this query,

SELECT CCUST
,CBLNAM
,RDCHGC
,RDQTY
,RDSIZE
,LEN(REPLACE(RDDYSR,'-','')) AS FREQ
,COUNT(RDDYSR)*RDQTY AS LIFTS
,RDSIZE * RDQTY * LEN(REPLACE(RDDYSR,'-','')) AS VOLUME
,FIRSTRDDYSR AS RDDYSR,FIRSTRDROUT AS RDROUT
,CASE WHEN (FIRSTRDDYSR LIKE 'M______') THEN RDQTY * RDSIZE END AS MON 
,CASE WHEN (FIRSTRDDYSR LIKE '_T_____') THEN RDQTY * RDSIZE END AS TUE
,CASE WHEN (FIRSTRDDYSR LIKE '__W____') THEN RDQTY * RDSIZE END AS WED
,CASE WHEN (FIRSTRDDYSR LIKE '___H___') THEN RDQTY * RDSIZE END AS THU
,CASE WHEN (FIRSTRDDYSR LIKE '____F__') THEN RDQTY * RDSIZE END AS FRI
,CASE WHEN (FIRSTRDDYSR LIKE '_____S_') THEN RDQTY * RDSIZE END AS SAT
FROM
(
    SELECT S.*, T.RDROUT AS FIRSTRDROUT, T.RDDYSR AS FIRSTRDDYSR FROM
    [SAMPLE] S
    INNER JOIN
    (
        SELECT CCUST, RDROUT, RDDYSR, ROW_NUMBER() OVER(PARTITION BY ccust ORDER BY (SELECT 1)) N
        FROM SAMPLE
    ) T ON S.CCUST = T.CCUST AND N = 1
) Tbl

GROUP BY CCUST, CBLNAM, RDCHGC, RDQTY, RDSIZE, RDDYSR, FIRSTRDDYSR, FIRSTRDROUT
