    Hello,

    You can either empty the destination table every time (DELETEALL;), and then re-insert every record from the source table. If you only want to update existing records in the destination table, then TRANSFERFIELDS and MODIFY should do it, like this, assuming that source and destination table definitions are identical:

    DestinationTable.GET(SourceTable.PrimaryKey);

    DestinationTable.TRANSFERFIELDS(SourceTable);

    DestinationTable.MODIFY;

    I hope you can use that?

    Hi, It seems that the record already exists when you insert it again, please check before insert.
    for example

    if destination.get(PrimaryKey) then
     exit;

    Hope this will help.

    Thanks.
