Recalculation of purchase price

38 Views

Dear All,

someone can help me to re-calculate the avarage cost price with a SQL script ?

we have the following script, but this just calculate the profit based on the last purchase price.

Our goal is to calculate the profit on the avarage cost price.

Thank you,

Giuseppe

declare @DocEntry as int

declare @Costo as numeric(19, 6)

declare @ItemCode as nvarchar(20)

declare @PrezzoCosto as numeric(19,6)

declare @PrezzoVendita as numeric(19, 6)

declare @Quantita as numeric(19, 6)

declare @LineNum as int

declare @TotUtile as numeric(19, 6)
