Can anybody help to resolve to remove link between change notice and change task?

This exception coming on wc11.1 only.

A persistence error occurred. System message follows:
Nested exception is: wt.associationRules.AssociationValidationException: Removing an association between "Change Notice - 00001" and "Change Task - 00001" violates the required role constraint of "Association Rule - PTC000007". The association is required for "Change Notice - 00001".

Please check sample code as below : 

// Get change Task here..
QueryResult changeActivityList = ChangeHelper2.service.getChangeActivities(changenotice);
while (changeActivityList.hasMoreElements()) {

//get ChangeTask obj
ChangeActivity2 changeActivity = (ChangeActivity2) changeActivityList.nextElement();

//get Affected obj
QueryResult qr2 = PersistenceHelper.manager.navigate(changeActivity,AffectedActivityData.ALL_ROLES, AffectedActivityData.class, false);
while (qr2.hasMoreElements()) {
AffectedActivityData affecteddata = (AffectedActivityData) qr2.nextElement();
ChangeHelper2.service.deleteAffectedActivityData(affecteddata);
System.out.println("deleted Affected Activity from Change task..!");
}

// get Resulting Obj.
QueryResult qr3 = PersistenceHelper.manager.navigate(changeActivity,ChangeRecord2.ALL_ROLES, ChangeRecord2.class, false);
while (qr3.hasMoreElements()) {
ChangeRecord2 changerecord = (ChangeRecord2) qr3.nextElement();
ChangeHelper2.service.deleteChangeRecord(changerecord);
System.out.println("deleted Resulting Data from Change task..!");
}
System.out.println("Change task name : "+changeActivity.getName());
System.out.println("Deleted change task started..!");
// delete change task.
ChangeHelper2.service.deleteChangeActivity(changeActivity);
System.out.println("Deleted change task success..!");
}

HI Windchiller,

Please use this API :

http://support.ptc.com/cs/wncdoc/110/wcapi/wt/change2/ChangeService2.html#deleteIncludeIn2AndChangeTask-wt.fc.collections.WTSet-wt.change2.ChangeOrder2-boolean-

here an example :

ObjectIdentifier oid= ObjectIdentifier.newObjectIdentifier("wt.change2.WTChangeActivity2:396443");
wt.change2.WTChangeActivity2 ct = (wt.change2.WTChangeActivity2) PersistenceHelper.manager.refresh(oid);


IncludedIn2 changeLnk = null;

WTSet myCT= new WTHashSet();
myCT.add(ct);
WTCollection list = new WTArrayList(PersistenceHelper.navigate(ct, IncludedIn2.ROLE_AOBJECT_ROLE, IncludedIn2.class, false));
for (Object o : list) {
changeLnk = (IncludedIn2) ((ObjectReference) o).getObject();
System.out.println(changeLnk.getChangeOrder2());
}
ChangeHelper2.service.deleteIncludeIn2AndChangeTask(myCT, changeLnk.getChangeOrder2(),false);

Good luck
