SQL Server Pivot Multiple Values - sql-server

Question

Using SQL Server 2012.
I have the following table. The Style and colour are passed as a parameter:
Style Colour Size Whse Stock Sales 4WeekSales ATP
ABC123 AS12 10 London 2 3 6 7
ABC123 AS12 12 London 4 6 8 10
ABC123 AS12 14 New York 6 8 9 12
ABC123 AS12 10 New York 7 5 7 5
But need the data to look like this with the sizes along the top:
Whse 10 12 14
Lon
Stock 2 4 6
Sales 3 6 8
4WeekSales 6 8 9
ATP 7 10 12
New York
Stock 7 6
Sales 5 8
4WeekSales 7 9
ATP 5 12
Points to note - the size field needs to be dynamic - sometimes it can be 6 /8/10/12, sometimes it can be XS/S/M/L etc
Also their are more than two whse's - this is just an example.
I did make a start in T-SQL:
use SafetyStock
go
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(Size)
FROM (SELECT p.Size FROM dbo.vw_optimums AS p
GROUP BY p.Size) AS x;
SET #sql = N'
SELECT SKU, Style,' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT SKU, Style, p.Size, p.SAFETYSTOCK
FROM dbo.vw_optimums AS p
) AS j
PIVOT
(
SUM(SAFETYSTOCK) FOR Size IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
However, this works but only pivots on the stock - how do I also pivot by Sales\4WeekSales\ATP and also groupb by the whse?
Thank you in advance.
This is my latest code. If I take the SEQNO out it works, but I need this so the sizes appear along the top correctly e.g. S / M / L / XL / XXL etc or 6/ 8 / 10 / 12
DECLARE #SizeColums VARCHAR(MAX)
DECLARE #Seq Integer
SELECT
#SizeColums = COALESCE(#SizeColums + ',','') + QUOTENAME([Size]),
#Seq = SEQNO
FROM vw_optimums1
GROUP BY [Size],[SEQNO]
ORDER BY [SEQNO]
DECLARE #Sql NVARCHAR(MAX) = N'
SELECT Whse,
[Types],' +
#SizeColums + '
FROM (SELECT * FROM vw_optimums1) t
UNPIVOT (
[Type]
FOR [Types] IN ([Stock],[LWSALES],[L4WSALES],[ATP]) ) up
PIVOT (
MAX([Type])
FOR [Size] IN (' + #SizeColums + ')
) p
'
EXEC sp_executesql #sql;

About the closest I can get you is this.
DECLARE #SizeColums VARCHAR(MAX)
SELECT #SizeColums = COALESCE(#SizeColums + ',','') + QUOTENAME([Size])
FROM vw_optimums
GROUP BY [Size]
DECLARE #Sql NVARCHAR(MAX) = N'
SELECT Whse,
[Types],' +
#SizeColums + '
FROM (SELECT * FROM vw_optimums
) t
UNPIVOT (
[Type]
FOR [Types] IN ([Stock],[Sales],[4WeekSales],[ATP]) ) up
PIVOT (
MAX([Type])
FOR [Size] IN (' + #SizeColums + ')
) p
'
This actually uses UNPIVOT first to get the breakdown by size, then pivots based on size.
You'll get a result like this based on the sample data.
Whse Types 10 12 14
-------- -------------- ----------- ----------- -----------
London 4WeekSales 6 8
London ATP 7 10
London Sales 3 6
London Stock 2 4
New York 4WeekSales 7 9
New York ATP 5 12
New York Sales 5 8
New York Stock 7 6
