Myslím, že vložení původního výrazu velkých písmen na správné místo by mělo fungovat. Zkuste toto:
PROCEDURE [dbo].[CreateLandingPurchaseOrderDetails]
-- Add the parameters for the stored procedure here
@startDate DATE, @endDate DATE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;
-- Insert statements for procedure here

SocietyMemberships.FromMinimumReturn AS '@FromMinimumReturn',
Deductions.DeductionRate AS '@DeductionRate',
CASE

Dotaz lze pravděpodobně vylepšit, ale bez definic tabulek a některých ukázkových dat je trochu obtížné jej otestovat.
Podívejte se na tento SQL Fiddle pro mírně vylepšenou verzi, která by měla poskytnout stejný výsledek.
