hi Soykan,

Well I would basically do a merge of the two tables

Then for each record there are the following possibilities

(1) in tableA and not in TableB
>>> insert into tableB

(2) in tableB and not in TableA
>>> insert into tableA

(3) exists in both tableA and tableB
You can do a scatter memo name for both tableA and tableB
You then compare each property of the two objects (with a loop (amembers()) and eval or macro subsitution)
In case there's a difference you will have to decide which one takes precedence over the other and change the object property
Finally you do a gather name obj memo one one or both the tables

Cannot help you much with this, the rules for precedence will have to be set up by you
