Prevent unauthorised changing of 'Ship to' field of Purchase order

Question

Hi experts
I am trying to prevent users from changing 'Ship to' field of Purchase Order without authorisation. OPOR.Address2
I am thinking to do this I should use a Stored Procedure which cause error if a condition is not met?
First I am trying to prevent any change of this field:
SP attempt:
--No changing of ship to address on PO
IF @object_type = '22' AND @transaction_type IN ('U','A')
BEGIN
IF EXISTS (SELECT T0.Address2 FROM dbo.OPOR T0 WHERE T0.Address2 <> (SELECT T1.CompnyAddr FROM dbo.OADM T1) AND T0.Address2 = @list_of_cols_val_tab_del)
SELECT @error = 1, @error_message = N'Direct shipment requires authorisation'
END
The above does not work - please can someone assist?
If there is better way to achieve my required outcome please advise me.
Thanks
Karen

Hi,
Try this:
IF @object_type = '22' AND @transaction_type IN ('U','A')
BEGIN
IF EXISTS (SELECT T0.[Docentry] FROM OPOR T0 WHERE T0.[Address2]  <> ( select T0.[CompnyAddr] from OADM T0) AND T0.docentry = @list_of_cols_val_tab_del)
SELECT @error = 1, @error_message = N'Direct shipment requires authorisation'
END
Thanks & Regards,
