Many companies have a need to grant Dynamics GP users access to a window, but not all functionality within that window. For example, many clients will want users to be able to input invoices, but not post them individually. Instead, they will force users to save invoice transactions to a batch such that a manager can review the source documents and post. An easy way to achieve this is through Field Level Security which allows the Dynamics GP admin to restrict user access to singular buttons within a window (such as the Post button).
To configure Field Level Security, navigate to Microsoft Dynamics GP > Tools > Setup > System > Field Level Security
This will open up the Field Level Security window. Within the window, select Add to create a new restriction.
This will open the Field Security Maintenance window wherein one defines a the window and field to restrict. Within this window, enter an ID and Description for the restriction. Then select the Product Name, Form Name, Window Name & Field Name using the look-ups within the window.
