inventory dimension security on SO form

I am trying to create a security group that would allow the user to edit the SO header (SalesTable) and SO Line(s) (salesLine) record that are already out there (not create or delete ) but am having some difficulty. I am using the security profiler tool from MS but even with that i can’t crack this one.

Currently, i have it so the groups grants view and edit to the salesForm form and the user can edit the SO header and lines with the exception of the inventory dimensions on the line. I granted full access (cascade) to the inventory dimensions table and still no dice. i’m wondering if anyone has figured this one out?

I figured this one out. there was datasource in the form that didn’t have any security around it so i set it up, added the perms to the group i was working with and thats fixed my issue.
