I want to give a security role access to edit the sales tax group and item sales tax group on purchase orders.
However, I am not able to restrict the access to only these fields. Below is a screenshot of the security configuration:
As you can see from the screenshots above, I have granted update-access to the display menu item PurchTablelistPage. For the references, I have denied permission to update/create/delete for all except TaxGroup.
When I test the role, it still has access to edit other fields in the purchase order. The ones highlighted in the screenshot above are only some of the fields I am able to edit.
How can I solve this case?
