RE: Account security question
There are more steps involved when enabling ALS..
1st step is to ensure it's activated : Administration >> Setup >> Company >> Company
make sure the checkbox for 'Account Security' is enabled.
2nd steps is to define the ALS levels : Administration >> Cards >> System >> Organizational Assignments
3rd you have to assign the Accounts to it : this can be in the same screen as above or in the Account card : Financial >> Cards >> Financial >> Account
Last step, the most important, is to assign those ALS levels to the users :
Administration >> Setup >> System >> User >> Select a user >> Organization button
Read carefully all the contextual help about Organizational Structures in GP :
mk:@MSITStore:C:\Program%20Files%20(x86)\Microsoft%20Dynamics\GP2013\GreatPlains.chm::/SMSUPart042OS.htm
The link above is for the Help in GP 2013.. but just open the main GP help file and search for the 'Organizational Structure' string.
Hope this helps..
