RE: When in the Vendor Maintenance window, I have a situation when I selects the E-mail option in the window. I am getting the GP message " You don't have security privileges to open this window. Contact your system administration for assistance
By default it doesn't seem like that operation is included in the CARD_0301 task that gives access to the Vendor Maintenance window. You can either have that added to the CARD_0301 task or create a new task and have it assigned to your role.

Specifically this reply:
"It is not sufficient to use the predefined tasks within GP as they do not include the required items. You must either add a task with new items, or add items to an existing task. If the Email Options window is all you need, then you need to add the "Email Options" window within whatever task you choose. In my example on April 1st, I added a new task called "EMAIL" to accomplish this. I then added this task to the "AP CLERK" role. It's generally considered good practice to create new tasks rather than editing existing tasks. However, the other option is to simply add this window to the task "CARD_0301" as follows:
Microsoft Dynamics GP > Tools > Setup > System > Security Task, Select "CARD_0301*", Product: Microsoft Dynamics GP, Type: Windows, Series: Company. Scroll down to "Email Options" and check it. Save and close. Have the user log out of GP and back in to ensure that the changes take effect. "
