RE: Direct write data into Business Central tables use ado
Hi,
As MahGah said, I also believe you are not able to write BC table on SaaS without API.
Regarding on premise, I think it is possible for external system to read/write BC table directly. BC is based on SQL server, so if external system have a proper permission to read/write BC table of database on SQL server instance.
Actually, I know such a case in NAV (former product of BC).
Of course, it's not recommended.
I hope this helps you.
