Hi Dave,

By default, only SAS Administrators are granted with the ability to add custom map provider.

Here is the documentation:
https://go.documentation.sas.com/doc/en/vacdc/8.5/varef/n0gvj6tc7l72t8n1e625v04x4vfb.htm

You would need to be a SAS Administrator or ask an administrator to grant access to /maps/providers to yourself or a group that you belong to.
