There is a table with a uniqe ID. This is an external time stamp table (yymmdd).I'd like to check if a fields (in the previous month) A colums, B columns and C columns have changed on the same ID in this table then we will update field  in the new table e.g: D:='Y'. If the table does not exist then do not nothing.

 

Thanks!
