call Command 'Transform Price List' and 'Update Cost' by script for Price List

Hello,

From screen  'Admisnistration Pricing', on view 'Price List' : applet 'Price List Applet' is defined with command 'Transform Price List' and 'Update Cost'. For my business requirement, I need to call associated method respectively 'UpdatePriceList' and 'PopulateCost'  by script in order to change currency or update cost.

Do you know on wich objects associated methods are defined  (business service or Business component )and how can we call this method (input propertyset definition for new currency...) ?

regards,

Jean-Marc
