Need an SP for UDO or UDT

Hi Experts

I need an SP for UDT or UDO  for SAP Business One

ex: I have fields like

Code                     Indent                shade  

1                              1234                    RED

2                               1234                    RED

Now it should throw an Error that  "Same Indent should not have same shade"

Code                     Indent                shade  

1                              1234                    RED

2                               1234                    Black

And if it is having different shade then it should get added or updated

I have written an SP  but it is not working

If(@object_type = 'OTP' and (@transaction_type = 'A' or @transaction_type = 'U'))

Begin

IF EXISTs (SELECT T0.U_Shade FROM  [dbo].[@OTP]  T0

WHERE T0.DocEntry = @list_of_cols_val_tab_del and T0.U_shade  not in

(select U_shade FROM [@OTP] WHERE U_Indent != T0.U_Indent and U_shade <> T0.u_SHADE ))

Begin

SET @error = 112

SET @error_message = N'same shade cannot be entered for same Indent'

End

END

please do workout on this and help us

Regards
