I think you are after the permissions on a dimension. Which are setup within burger menu Administration / Databases / Select your database Name / Users (Which is a tab)
Then in there, look to the immediate left of the Default Period selected for a user. There is a little Padlock icon. Pressing that, lets you select a dimension - in your case, G/L Accounts dimension which I am hoping is a dimension?, then for that user, select which accounts you allow them to see by settings up an “Equals to” rule, selecting the accounts from the […] button list.
I use this method for our G/L database. Then it restricts all the values down to that selected list of accounts for that user.
It’s a little bit of a pain, but I just got the accounts department to setup a spreadsheet of the names along the top and the accounts down the left column, then put a X in the cells where those names are allowed those accounts. They maintain that sheet, and if there are changes, they email me over the spreadsheet.
Maybe in a future enhancement, Phocas might give us a way to Sync this kind of spreadsheet to use as an Input to a list of security permissions like this one. Although the G/L is a specific case where this kind of updating is a bit of a pain, especially when there are loads of users and accounts to allow permissions to… hmm More of Rich’s ramblings, sorry
Back on topic, the users who need all accounts, you of course don’t need to bother with the Padlock permissions, only the few users who are only allowed certain accounts.
I also restrict some people from seeing data about salaries by selected “Not Equal” to type rule, against certain expense codes. Hope this leads you down the road you are after and not up the garden path?
