Cost Estimate in Mass

Dear Experts

Is there any way to calculate cost estimate in mass.

I have to release standard cost of around 2000 codes.

We are using ck11n for cost calculation and then saving of estimated cost in ck24

I am unable to create BDC for the same,beacuse BDC recording stops once cost is calculated ,it does not propt for another code.

Thanks in Advance.
