Hi ravmitterhoff,
I had a quick look on the https://community.canvaslms.com/docs/DOC-12595-421441905 page, and unfortunately OpenEduCat ERP is not supported.
For institutions that wish to use an unsupported ERP there are several options. Firstly, the institution can engage Canvas' professional services for a quote to undertake an integration. Alternatively (and what more institutions tend to do) is build their own set of integrations. Some might use scripting, while others might use full blown tools such as IBM Message Broker to build a set of integrations using the APIs on both the LMS and the SIS.
Hope that helps!
Stuart
