Can i have an object from Rollbase that is related to an object from OpenEdge where the Rollbase object is the many in a many to one relationship?

Yes, you can.   But you can’t do it the other way.
 
The relationship to OE objects is stored in a Rollbase Object as a Foreign-Key field to the OpenEdge Object.  So MANY Rollbase “Contacts” could be associated to 1 OpenEdge “ttCustomer”.     

To create it, go to the OpenEdge Service Object (‘ttCustomer’), and define a New Relationship – select the Rollbase “Contact” and it gives you two choices:  1 ttCustomer to 1 Contact, and 1 ttCustomer to Many Contacts.

Hi Jason,

Are you trying to create objects from OpenEdge Services? As per documentation, relationships involving OpenEdge objects support only the following scenarios:

> 1-1 or 1-N cardinality when establishing a relationship between an OpenEdge object and another OpenEdge object or a Rollbase Native object.
> 1-1 or N-1 cardinality when establishing a relationship between a Rollbase Native object and an OpenEdge object.

Please refer to this link for more information: http://documentation.progress.com/output/Rollbase/index.html#page/rb/Rollbase.291.html


Hope this helps,
Godfrey
