Recalculating Resource Plan Allocated Cost since rate card correction

[Uncle Rob]

SCENARIO:
Resource plan created, generating requested_allocations.  resource_plan.planned_cost calculates correctly since its using the group_resource rate.

Because of the FiretrUCKING Labor Rate Card table swapping bug, hundreds of allocations have been created with the wrong resource_allocation.allocated_cost.  That means resource_plan.allocated_cost is also borked.

Deconstructing the ResourcePlan script include I've found functions that allow me to recalculate planned cost, however no functions appear to recalculate and update a resource_allocation's allocated_cost, then recalculate the resource_plan.allocated_cost.  

Anyone have any insights?

Here's a script I've been working with.  updatePlanned() works, but updateAllocated() does nothing.

function updatePlanned(req) {
	var resourcePlan = new ResourcePlan();
	resourcePlan.get(req.getValue('resource_plan'));
	resourcePlan.updatePlannedHoursAndCost(req.getTableName());
}

function updateAllocated(alloc){
  gs.print('in updateAllocated');
	var allocation = new ResourceAllocation(alloc);
	allocation.calculateAllocatedCost();
	var resourcePlan = new ResourcePlan();
	//gs.print(alloc.getValue('resource_plan'));
	resourcePlan.get(alloc.getValue('resource_plan'));
	//resourcePlan.updateAllocatedCost();
	resourcePlan.updateAllocatedHoursAndCost();
}

var rp = new GlideRecord('resource_plan'); 
rp.get('37313f471383e34084b3b7a66144b00c'); //my sample Resource Plan
gs.print(rp.short_description);

var rpreqs = new GlideRecord('requested_allocation');
rpreqs.addQuery('resource_plan',rp.sys_id);
rpreqs.query();
while (rpreqs.next()){
  updatePlanned(rpreqs);
}

var rpallocs = new GlideRecord('resource_allocation');
rpallocs.addQuery('resource_plan',rp.sys_id);
rpallocs.query();
while (rpallocs.next()){
  gs.print('Launch updateAllocated');
  updateAllocated(rpallocs);
}

Hey Harsha,
Isn't that the exact same code, just with the commented lines knocked out?

EDIT:  Wait!  Nope, I'm just blind.  Thanks for the tip.  I'll try this!

No. You are calling 

allocation.calculateAllocatedCost();

If you see the actual code, it just sets allocated cost but doesn't update.

I am calling

allocation.updateAllocatedHoursAndCost();

which actually updates hours and costs as well.

DUDE!  Thank you!

[Uncle Rob]

So grateful for this, Harsha.
If you have the time, could you explain why its got to run ResourceAllocation.updateAllocationHoursAndCost as well as ResourcePlan.updateAllocatedHoursAndCost?
