In SAS® Enterprise Guide® 8.3, SAS® Enterprise Guide® 8.4, and SAS® Enterprise Guide® 8.5, the following error occurs:

This issue occurs when you complete steps similar to the following:
Scenario One
- Submit the LIBNAME statement twice with access=readonly in a way that overwrites a library already defined in pre-assign.
- Refresh the library.
Scenario Two
- Submit a LIBNAME statement on SASApp. For example, libname test "c:\temp";.
- Expand the Libraries in the Servers list to view the TEST library.
- Submit the same LIBNAME again with the access=readonly: libname test "c:\temp" access=readonly; option.
- Right-click Libraries in the Servers list and click Refresh. The icon for the TEST library now contains a lock icon because it is read-only.
- Click the TEST library to open it. The error occurs.
Scenario Three
- First, choose to submit the read-only library.
- Open the Libraries branch of the Server-Tree. Then, submit the LIBNAME to make it writable.
- Refresh the library. The error occurs.
There is no workaround for this issue.
The issue is fixed in SAS® Enterprise Guide® 8.6.
