select unique and return related table

[Microblitz]

This Code selects a unique entry of the Manufacturing Order.

DECLARE @suffix NVARCHAR(8)
DECLARE @DateStart NVARCHAR(12)
DECLARE @DateEnd NVARCHAR(12)

SET @suffix = '/M'
SET @DateStart = '01/05/2013'
SET @DateEnd = '08/05/2013'

SELECT a.*  from  ManufacturingOrders a 
INNER JOIN
(SELECT DISTINCT  ManufacturingOrderId FROM ManufacturingOrders) AS b
ON a.ManufacturingOrderId = b.ManufacturingOrderId
ORDER BY ManufacturingOrderId

I need to use that to select related information from this query.

SELECT     ManufacturingOrders.QuantityMade AS Quantity_Made, Products.ProductId, Classifications.ClassificationId, Products.ProductDescription, 
                      ManufacturingOrders.QuantityOutstanding AS Outstanding, ManufacturingOrders.DueDate, ManufacturingOrders.ReleaseDate, 
                      ManufacturingOrders.ManufacturingOrderId, Inventory.EffectiveDate, Inventory.CreatedDate, Inventory.LotNumber, Inventory.WorkInProgress, 
                      Inventory.QuantityFilled

FROM       ManufacturingOrders INNER JOIN
                      Products ON ManufacturingOrders.Product = Products.Product INNER JOIN
                      Classifications ON Products.Classification = Classifications.Classification INNER JOIN
                      Inventory ON ManufacturingOrders.ManufacturingOrder = Inventory.ManufacturingOrder AND Products.Product = Inventory.Product
WHERE     (RIGHT(Products.ProductId, 2) = UPPER(@suffix)) AND (dbo.wfn_GetSimpleDate(Inventory.CreatedDate) BETWEEN @DateStart AND @DateEnd)
ORDER BY Classifications.ClassificationId, ManufacturingOrders.ReleaseDate DESC

Can anyone suggest how I can tack these two pieces of code together without dropping data. Essentially I need to get the data from the second query ONLY if its the first occurance of the Manufacturing order so I can return the correct requested order amount as there are multiple instances of the Manufacturing order table (I know somebody (not me) messed up!)

I'm not sure I understand your question. Some sample data and results would help.

I rewrote this and solved it.

Glad you got it fixed. Can you post your solution in case someone else runs into the same situation?
