Ax2009 security

Hello team,

I know that security was tightened in Ax2009, but I am not clear about the implication of that. I seem to end up with big problems because I don’t understand this.

Can someone please tell me (or point me to some links ) how the following works in Ax2009?

  1. If I add new fields to an existing table like purchtable, what security is applied to these fields.

  2. Does adding new fields to purchtable affect the functioning of any classes associated with purchtable, for eg. purchtableform class that implements syssaveable.
