When creating an OBN link, you can specify that the navigation target selected at runtime is from the same role that contains the source iView.
More information: Creating an OBN Link .
When creating the IOBNMetadata object for creating an OBN link, add a parameter that specifies that you want to navigate only within the current role, that is, the role that contains the iView that contains the OBN link. For example:
// Create the OBN factory IOBNService obnService = (IOBNService) WDPortalUtils .getServiceReference(IOBNService.KEY); OBNFactory obnFactory = obnService.getObjectsFactory(); // Create an OBN metadata object (valid for both technologies) IOBNMetadata obnMetaData = obnFactory .createOBNMetadata("myBO","","myOp",getUser()); // Create an OBN parameter for source role navigation String navModeName = com.sap.portal.obn.service.IOBNConstants.IOBNUrl .IParameters.NAVIGATION_PARAM_NAVIGATE_MODE; String navModeValue = com.sap.portal.obn.service.IOBNConstants.IOBNUrl .IParameters.IParametersValues.NAVIGATE_MODE_SOURCE_ROLE; IOBNParameterData sourceNavModeParam = myOBNFactory .createOBNParameterData(navModeValue); // Add parameter to OBN metadata myMetaData.setParameter(navModeName , sourceNavModeParam);
