When using a custom API in Dynamics 365, the primary column name for most tables is "tablename + id," except for the "systemuser" and "team" tables, which use "ownerid" instead of "systemuserid" or "teamid." This is because both "systemuser" and "team" inherit the "ownerid" property from the "principal" entity type. The "ownerid" value is the same as the respective "systemuserid" or "teamid" columns.
