Nowadays, we have no way to know, solution wide, if there're records that are opened, and that hence lock the record.
Knowing that is important because it can help to avoid / mitigate 729 errors (when doing a replace all, or an import). It's also imortant for an admin to know if he can safely disconnect clients or not.
The proposed Get ( OpenedRecordIDs ) would ask the server for opened records and it would return an "array" = tab separated value list containing :
The RecordID of the opened record, the Table name, the filename, the user name
So we could know everything and eventually warn the user that has an opened record. That may also serve as a locking detector to eventually explain some performances issues
