Does anyone have experience working with the BOMCalcJob_All class

I have a project to automate Costing version.  This form is located in Inventory and warehouse management --> Costing --> Costing version.  Basically create a new costing version automatically add all bom items to the new costing version and perform the bom calculations for the new costing version.  I'm able to accomplish steps 1 and 2, but not able to find any examples for performing the BOM calculations using the BOMCalcJob_All class.  Does anyone have any experience or examples on using or performing this step?

1. Create a costing version record.  Done...
2. Perform "Copy Last Cost" to new costing version.  Done..
3. Perform "BOM or formula calculation results". 

Need assistance
