As the idea name states, it would be great to have an option when copying a company to turn on options to clear transactional data and also reset no. series (clear the Last No. Used). There would need to be a new property added to tables (that can also be set on app/extension tables) to indicate which tables are considered transactional. Maybe a third option to clear master data (customers, vendors, items, etc.). So, I guess my suggestion would be to add a classification property to tables to mark the data type (Master Data, Transaction, Document, Other) and then options when copying a company to clear the various types of data...plus the No. Series option as well.
