Check calculation through SP

Question

Hi All,
I have a scenario where I have to make sure that the correct lot quantities (udf's) are entered based on the quantity in sales quotations. The user may or may not use all the lot quantities. The requirement is like this:
Quantity - (Lot1Lot2Lot3) = 0 If the value is not zero, the user should get a message so that he could correct the quantities. I have a SP which validatesd it only for one udf. How can I get the calculation checked??
DeClArE @Lotnum1  int
Declare @Lotnum2   int
Declare @LOtnum3   int
Declare @Qty       int
IF (@Object_type = '23' AnD @transaction_type IN (N'A', N'U'))
BeGIN
sELECt @Qty= T1.Quantity, @Lotnum1=T1.U_Lot1,  @Lotnum2=T1.U_Lot2,  @Lotnum3=T1.U_Lot3    from QUT1 T1 where docentry=@list_of_cols_val_tab_del
eNd
if (@Qty != @Lotnum1  )
begin
SET @error = 15
SET @error_message = @list_of_cols_val_tab_del +'Calculation of lots is not correct'
end
Please assist.
Thanks,
Joseph

Dear jyo
As per your Scenario. I am giving you the Exact Query which i have make for our Company . Please Try this .
Create Table #temp
  ItemCode varchar(200),
  Linenum  int,
  Docentry varchar(20),
  Qty      Decimal(19,2),
  Lotnum1  Decimal(19,2),
  Lotnum2  Decimal(19,2),
  Lotnum3  Decimal(19,2),
  Lotnum4  Decimal(19,2),
  Lotnum5  Decimal(19,2)
Declare @Lotnum1 int
Declare @Lotnum2 int
Declare @Lotnum3 int
Declare @Lotnum4 int
Declare @Lotnum5 int
Declare @ITemCode varchar(200)
Declare @Linenum    int
Declare @Docentry  varchar(20)
Declare @Qty int
Declare @Status int
Declare @ErrorItm varchar(5000)
Set @Lotnum1=0
Set @Lotnum2=0
Set @Lotnum3=0
Set @Lotnum4=0
Set @Lotnum5=0
Set @Status=0
Set @Qty =0
set @ErrorItm=''
IF (@Object_type = '23' AnD @transaction_type IN (N'A', N'U'))
BEgin
Insert into #temp
Select ItemCode, LineNum,Docentry,Quantity,U_Lot1,U_Lot2,U_Lot3,U_Lot4,U_Lot5 from QUT1 where Docentry =@list_of_cols_val_tab_del
End
DECLARE C1 CURSOR FOR SELECT DISTINCT ItemCode, LineNum,Docentry FROM #temp
     OPEN C1
     FETCH NEXT FROM C1 INTO @ITemCode,@Linenum,@Docentry
     WHILE @@FETCH_STATUS = 0
     BEGIN   
    Set @Lotnum1 =(Select isnull(Lotnum1,0) from #temp where LineNum=@Linenum)
    Set @Lotnum2 =(Select isnull(Lotnum2,0) from #temp where LineNum=@Linenum)
     Set @Lotnum3 =(Select isnull(Lotnum3,0) from #temp where LineNum=@Linenum)
    Set @Lotnum4 =(Select isnull(Lotnum4,0) from #temp where LineNum=@Linenum)
    Set @Lotnum5 =(Select isnull(Lotnum5,0) from #temp where LineNum=@Linenum)
    Set @Qty =(Select isnull(Qty,0) from #temp where LineNum=@Linenum)
If (@Qty !=(@Lotnum1@Lotnum2@Lotnum3@Lotnum4@Lotnum5))
Begin
set @Status = @Status+1
Begin
Set @ErrorItm = @ErrorItm ' ' @ITemCode
End
End
FETCH NEXT FROM C1 INTO @ITemCode,@Linenum,@Docentry
     END
CLOSE C1
DEALLOCATE C1   
--Begin
--SELECT @Qty= T1.Quantity, @Lotnum1=isnull(T1.U_Lot1,0), @Lotnum2=isnull(T1.U_Lot2,0), @Lotnum3=isnull(T1.U_Lot3,0), @Lotnum4=isnull(T1.U_Lot4,0)
-- from QUT1 T1
--where
-- docentry=@list_of_cols_val_tab_del
--eNd
if (@Status != 0 )
begin
SET @error = 15
SET @error_message =  @ErrorItm ' ''Calculation of lots is not correct'
end
--end
Please try this query I think you get the Solution
Thanks
