Люди, нашёл!
оказывается остался лишний код от "Аxапта 3.0 СП4 ЕЕ" в Application класе.
X++:
// No SYS code must exist in this method
// If you need the startup command, look in the class SysStartupCmd
void startupPost()
{
//--- CRM start
/*
if (!appl.isConfigMode())
{
//--- Prevent call to smmInit during installation of Axapta
//--- If not, code in the method below is run that uses a table that has not yet been created
SmmInit::initFromServer();
}
*/
//--- CRM end
}
