Block Goods Issue base on Projects if null

Question

i have this requirement in SP
Scenario.
i want to block Goods Issue base on the ff. requirement
1. if Project is Null it will block adding the Goods Issue if U_Department and U_Section is empty
2. if Project is not Null i will allow adding the Goods Issue even the U_Department and U_section is null
base on this requirement i made an SP but it doesn't work.
--      Make Department Mandatory in Goods Issue
IF (@object_type = '60') and (@transaction_type IN (N'A', N'U'))
BEGIN
     IF EXISTS (SELECT T0.Docentry from OIGE T0 Inner Join IGE1 T1 ON T0.Docentry=T1.Docentry where
     T1.DocEntry = @list_of_cols_val_tab_del and (T1.Project is not null and T0.U_DEPT is null or T0.U_DEPT ='' ) )
     BEGIN
          Select @error = 10, @error_message = N'Department Must be filled-up!'
     END
END
--      Make Section Mandatory in Goods Issue
IF (@object_type = '60') and (@transaction_type IN (N'A', N'U'))
BEGIN
     IF EXISTS (SELECT T0.Docentry from OIGE T0 Inner Join IGE1 T1 ON T0.Docentry=T1.Docentry where
     T1.DocEntry = @list_of_cols_val_tab_del and (T1.Project is not null and T0.U_SECT is null or T0.U_SECT =''))
     BEGIN
          SET @error = 10
          SET @error_message = N'Section Must be filled-up!'
     END
END

hi Avelino Fidel try this try this final query ,it will work
IF (@object_type = '60') and (@transaction_type IN (N'A', N'U'))
BEGIN
IF EXISTS (SELECT distinct  T0.Docentry from OIGE T0 Inner Join IGE1 T1 ON T0.Docentry=T1.Docentry where
T1.DocEntry = @list_of_cols_val_tab_del and (isnull(T1.Project,'') = '')  or  (isnull(T0.U_DEPT,'') = '' ) )
BEGIN
Select @error = 10, @error_message = N'Department Must be filled-up!'
END
END
