Extending user table

Posted on by Valentine Motin

Hello everyone,

I came across the error "The system or virtual table "User" cannot be extended".

I read in the microsoft documentation that system tables cannot be extended, however in "Programming Microsoft Dynamics 365 Business Central" by Mark Brummel, there's a paragraph saying that "with full developer license rights, we can modify system tables to extend their usage".

So, is it possible to extend the User table in Business Central 16 ?

Thanks in advance

You can't extend the User table. What you can do is extending User Setup table. Use the User Setup table for what you are trying to do.

RE: Extending user table

Hi,

from the official documentation there is written:

##

System and virtual tables cannot be extended. System tables are created in the ID range of 2.000.000.000 and above. For more information about object ranges, see Object Ranges.
