Record lock for multiple user access in Base

[Mo2e]

I am going to write a Base app connecting to Sybase via JDBC to replace existing Access app. The app needs to support multiple user editing. Warning message is pop up if one tries to overwrite update of another in Form. I could do it easily in Access if i tick the option “Open databases using record-level locking”. However, i couldn’t find someting similar in Base and it always overwrite update of another without any message. Could anyone give some advise?

I have found in the LibreOffice help:

Edit Data
Editing Databases in Networks
To make changes in a database used by more than one person, you must have the appropriate access rights. When you edit an external database, there is no intermediate storage by LibreOffice of the changes made. They are sent directly to the database.

Thanks, mariosv. I was thinking to implement a simple version control. I go ahead after reading your reply.
