I'm trying to insert the base price of an Inventory Item ( Base Price is in the Pricing Tab of the form to insert Inventory Items ) but I don't know what property of the inventory item class is associated with this field, I'm doing this:

public Boolean insertInventoryItem()          {              this.login();                                        InventoryItem invItem= new InventoryItem();                invItem.itemId = itemId;              invItem.mpn = mpn;              invItem.purchaseDescription = description;              invItem.isTaxable = true;              invItem.isTaxableSpecified = true;              ...              invItem.basePrice = ¿? ( I don't know what property is it, in order to be  able to assign a value)                WriteResponse response = _wsNetSuite.add(invItem);              this.logout()              return response.status.isSuccess;          }
