hi Ive

Since resource scheduling doesn't have any functions in the service definition to assign resources to, TrySwapResource won't do for this use case indeed.

Booking.AssignResources() can be used here. Support to assign resources has been added since SRM 1.2.19. The resource that needs to be swapped can be unassigned using booking.UnassignResources().

Example AssignResources()

var request = new AssignResourceRequest
{
TargetNodeLabel = "", // When assigning a resource unmapped the `TargetNodeLabel` needs to be null or empty.
NewResourceId = resourceIdToAssign,
ProfileInstanceId = profileInstanceIdByRef, // ID of the Profile Instance to assign by reference. Use `Guid.Empty` to not set or remove the Profile Instance.
InterfacesProfileIntanceId =
{
{ interfaceId, interfaceProfileInstanceIdByRef }  // ID of the interface and the Profile Instance to assign by reference for that interface. Use `Guid.Empty` as value to not set or remove the Profile Instance.
},
IsContributing = false, // Set to `true` when assigning contributing resource
};
booking = booking.AssignResources(Engine, request);

Example UnassignResources()

To unassign a resource, a new method UnassignResources has been added:
var request = new AssignResourceRequest
{
TargetNodeLabel = "", // When unassigning a resource unmapped the `TargetNodeLabel` needs to be null or empty.
NewResourceId = resourceIdToUnassign,
};
booking = booking.UnassignResources(Engine, request);
