Checking the duplication of batch number

Question

hi expert
       I m using the Stored procedure (SP_TranscationNotification) for checking the duplication for Batch Number ie when a alreasy existing batch number is given an error message should be shown.
      declare @ItemCode nvarchar(64)
      declare @batchNumber nvarchar(64)
      if @transaction_type in ('U','A') and (@object_type='106')
         begin
            set @itemCode = LEFT(@list_of_cols_val_tab_del, CHARINDEX(CHAR(9),  @list_of_cols_val_tab_del,1)-1)
               set @batchNumber=substring(@list_of_cols_val_tab_del,charindex(char(9),@item)+1,len(@list_of_cols_val_tab_del))
             if exists(select @itemcode,@batchnum from OIBT where BatchNum=@batchNumber and ItemCode=@Item)
                begin
                    select  @error = 1, @error_message ='batch number already exists'
                end
        end
     Here in the above SP , i cant able to get the batch number,Please anyone give me the solution of getting batch number or suggest a method to get the value between first and second tab of a row.

Please check this answered link. Your level of batch would be defined on plant, thats why you are getting duplicate batches. Batch definition at Client level has unique batch numbers.
Change the Batch Level
