Hi @Filipvdr
First, you may want to check the log, available from %appdata%\SAS\SASManagementConsole\9.4
If there isn't any helpful information, please turn on debug with Usage Note 43157 (Capturing debugging messages from SAS® Management Console).
Overall, without jumping to conclusion, it's possible that the issue is caused by a corrupt resource template.
Before proceeding with below steps, please ensure you have a backup.
Once the backup has completed and you have verified that it was successful, please do the following:
1- Log into SAS Management Console as your unrestricted admin user (eg. sasadm@saspw).
2- Expand the Metadata Manager plug-in and click on the Resource Templates folder.
3- In the right pane, scroll down until you see the SAP Library template. Right-click on it and choose "Delete".
4- In the left pane, right-click on the Resource Templates folder and choose "Add Resource Template".
5- In the first screen of the wizard, leave "Typical" selected and click "Next".
6- In the next screen, expand Libraries, expand Enterprise Applications Data.
7- Select SAP Library and click Next.
8- Click Finish to re-load the template.
Does that give you access to the Properties ?
Hope that helps.
Cheers,
Damo
