I try to assign a resource (belonging to the same company, site, resource groups etc.) via API-Calls to a task in a request. Unfortinately I can’t set application constraints to false to set a resource to this task? Has anyone an idea how to do this?

The code-sequence is:

json = $"{{\n";                                                                 // Assign Work
json += $"  \"ApplyConstraints\" : false , ";
json += $"  \"AllowMultipleVisits\" : false , ";
json += $"  \"Description\" : \"{Description}\" , ";
json += $"  \"ExcludeFromScheduling\" : false , ";
json += $"  \"Duration\" : {Duration} , ";
json += $"  \"TaskSeq\": {TaskSeq} ";
json += $"\n}}";

endpoint = $"main/ifsapplications/projection/v1/AssignWorkHandling.svc/ExecutionInstanceSet";

response2 = await PostData2(endpoint!, json);

…..

json = $"{{\n";                                                                 // Modify Settings
json += $"  \"TaskSeq\" : {TaskSeq} ,   ";
json += $"  \"ParentTempObjkey\" : \"{ObjkeyTask}\"  ";
json += $"\n}}";

endpoint = $"main/ifsapplications/projection/v1/AssignWorkHandling.svc/ModifySettings";

response2 = await PostData2(endpoint!, json, "", eTagTask);

…...

json = $"{{\n";                                                                 // Apply Constraints = false (2nd try)
json += $"  \"ApplyConstraints\" : false,   ";
json += $"  \"Objsite\" : \"{Objsite}\"  ";
json += $"\n}}";

endpoint = $"main/ifsapplications/projection/v1/AssignWorkHandling.svc/ExecutionInstanceSet(Objkey='{ObjkeyTask}')/ExecutionInstanceSelectorArray(Objkey='{ObjkeyTask}')?";

response2 = await PatchData2(endpoint!, json, "", eTagTask);

json = $"{{\n";                                                                 // Assign Resource, Date, Time
json += $"  \"ApplyConstraints\" : false , "; 
json += $"  \"Objsite\" : \"{Objsite}\" , ";
json += $"  \"TaskSite\" : \"{Objsite}\" , ";
json += $"  \"TaskSeq\": {TaskSeq}, ";
json += $"  \"AdjustSchedule\" : false , ";
json += $"  \"AllocatedHours\" : {Duration} , ";
json += $"  \"AllocatedStart\" : \"{AllocationStart}\" , ";
json += $"  \"AllocatedFinish\" : \"{AllocationEnd}\" , ";
json += $"  \"AllowMultipleVisitsDb\" : false , ";
json += $"  \"AllowMultipleVisits\" : false , ";
json += $"  \"FixedResource\" : false , ";
json += $"  \"AdjustToSchedule\" : \"NoAdjustToSched\" , ";
json += $"  \"ExcludeFromScheduling\" : false , ";
json += $"  \"ResourceType\" : \"PERSON\" , ";
json += $"  \"ResourceId\" : \"{ResourceId}\" , ";
json += $"  \"ResourceSeq\" : {ResourceSeq} , ";
json += $"  \"Description\" : \"{Description}\" , ";
json += $"  \"TaskResourceSeq\": 1 ";
json += $"\n}}";

endpoint = $"main/ifsapplications/projection/v1/AssignWorkHandling.svc/ExecutionInstanceSet(Objkey='{ObjkeyTask}')/ExecutionInstanceSelectorArray(Objkey='{ObjkeyTask}')/TaskDemandArray(Objkey='{ObjkeyTask}')/TaskDemandAllocArray";

response2 = await PostData2(endpoint!, json,"", eTagTask);

The last Post-Call throws an execption: no resource

Any Idea how do solve this for many thousand requests?
