Dynamics GP - "You don't have security priveleges to open this window" when printing an SOP invoice

Problem:
You get a security error when trying to print an SOP invoice even when you have all the correct security setup.

this problem occurs if you have manufacturing installed.
Security for an additional window is required to print invoices.

Solution:
Add access to the SOP_Dummy_Report_Form

1. I suggest adding the security to the DefaultUser Task ID
2. Assign the Defaultuser task id to all of the Roles
1. Tools>System>Security Role
2. Select Role
3. Find and Tick defaultuser
3. Go to Tools>Setup>System>Security Tasks
4. Select Defaultuser
5. select Product: Manufacturing
6. Select type: Windows
7. Select series: 3rdparty
8. Scroll down to SOP_Dummy_Report_Form
9. Tick it
10. Save
11. Let users close GP and login again
12. You should be able to print invoices properly now
