I have found that the easy way to grant security is going to the screen as an admin and then using the Access Rights

Hello @jwarren 

As @dboes14  suggested you can grant the relevant access for the user role in the below path

Access Rights by Screen > Payables > Vendor Location

Before

After

Hello @jwarren!

I set up a test role and got the same error message.

Here are the steps taken to resolve.

• Logged in as admin, then went into Payables > Profiles > Vendors
• Clicked on one of the vendors, went into the Locations tab, then clicked the + sign to add a new location

• This brought up the Vendor Locations (AP303010) screen where I clicked Tools > Access Rights

• This brought up Access Rights by Screen in a new tab where I was able to determine the appropriate access node for this
• If you hover the mouse over these access nodes, the screen id will show, enabling you to verify you are in the right access node

• As shown in the screen shot above, I gave the TEST role Delete access to Vendor Locations … Insert access would probably work there as well
• Test user can now add vendor locations without error
