How to add "SatisfiedBy/satisfies" link in DNG workitem through OSLC API?

Hi All,

I am working on task where I have to update DNG artifact with link("SatisfiedBy/satisfies"). I am using OSLG4j(OSLC client) for developing my stand alone application. I am able to add link of type "SpecifiedBy/Specifies" in DNG artifact through my code, but not able to add "SatisfiedBy/satisfies" link.

Sample code

Requirement req = response.getEntity(Requirement.class);
String etag = response.getHeaders().getFirst(OSLCConstants.ETAG);
ClientResponse updateResponse = null;
                        req.addSatisfiedBy(new Link(new URI(artifact.getKey()), artifact.getValue()));
                        updateResponse = client.updateResource(resultsUrl, req, OslcMediaType.APPLICATION_RDF_XML, OslcMediaType.APPLICATION_RDF_XML, etag);
                        if(updateResponse.getStatusCode() ==HttpStatus.SC_OK) {
                            System.out.println("Requirement updated successfully with requirement : " + artifact.getValue());
                        } else {
                            System.out.println("Issue while updating requirement..............." +  artifact.getValue());
                        }

When I run this code I am getting response 200 but unable to see link in Doors artifact. Is there any linitation on adding by OSLC rest api?
        
          
Could you please let me know how to achieve same?

Thank you in advance
