Dear Nagarajan K.
                     Thanks for your replay ..
IF @transaction_type IN ('A','U') AND (@object_type = '106' )
BEGIN
set @item = LEFT( @list_of_cols_val_tab_del, CHARINDEX(CHAR(9),  @list_of_cols_val_tab_del,1) - 1)
set @batch = substring(@list_of_cols_val_tab_del, len(@item)+1, (CHARINDEX(CHAR(9),  @list_of_cols_val_tab_del,len(@item)+2)) - (len(@item)+1))
--set @base =( select basetype from ibt1 where batchnum = ltrim(rtrim(replace(@batch,char(9),''))))
set @count = (select count(*) from oibt quantity > 0 and where  batchnum = ltrim(rtrim(replace(@batch,char(9),''))))
if @count > 1
begin
set @error = 1
set @error_message = 'Please enter different Batch Code for batch ''' + @batch + ''' for item ' + @item 
select @error, @error_message
END
END
              I used above Stored Procedure. here we can use one batch number for different item but  i want to block one batch we should use one item and one time only after than we never use that batch number for same item and another item.
         After that I want format for Batch, we should follow unique Batch number for all items.
