You need to use: @@IDENTITY(T-SQL)[^] instead SCOPE_IDENTITY()

SQL

DECLARE @InvoiceNo INT
DECLARE @InvoiceProductNo INT

INSERT INTO Invoice ([Date])
VALUES (GETDATE())

SELECT @InvoiceNo = @@IDENTITY()

INSERT INTO InvoiceProduct([InvoiceNo])
VALUES (@InvoiceNo)

SELECT @InvoiceProductNo = @@IDENTITY()

INSERT INTO InvoiceProductExp ([InvoiceProductNo], [InvoiceNo])
VALUES (@InvoiceProductNo, @InvoiceNo)
