Issue with complex query "the multi-part identifier could not be bound" - sql

Question

I am having trouble creating this view on SQL. As a query, it runs fine, but when trying to save it as a view, it gives me the "the multi-part identifier could not be bound" error. I think it has something to do with implicit joins.
The issue occurs when inserting the part with the extra tabs in the script below (case statements).
Is there a way to rewrite it to save it as a view?
Thanks

Answer 1

I found a solution:
Instead of adding MNP and INV as WITH statements within the query, I created them as separate views which I referenced to within this new query which I could now save as view.
Script ended as follows:
SELECT
GR.ID,
GR.VL_Ref,
GR.DateReceived,
MNP.Manip_Start_Date,
COALESCE (DATEDIFF (Day, GR.DateReceived, MNP.Manip_Start_Date),'') AS DaysToManipulate,
WR.Name AS Warehouse,
GR.ArticleOriginID AS Origin,
SP.Name AS Supplier,
GD.Name AS Grade,
COALESCE(INV.Invoice_TOT,0) AS Invoice_TOT,
COALESCE(INV.Invoice_Units,0) AS Invoice_Units,
COALESCE(INV.Invoice_KG,0) AS Invoice_KG,
COALESCE(MNP.Total_Units,0) AS ManipulatedUnits,
CASE WHEN MNP.Total_Units IS NOT NULL THEN MNP.Total_Units - INV.Invoice_Units ELSE 0 END AS Manip_Difference,
COALESCE(MNP.TEX_Mnp,0) AS TEX_Mnp,
COALESCE(MNP.ACC_Mnp,0) AS ACC_Mnp,
COALESCE(MNP.SHOE_Mnp,0) AS SHOE_Mnp,
