Is there a command in Inventor to add values in a column in the Part list ( BOM) and to display a total value bottom like the Grand Total in Revit?
Not aware of one, but you can create this in Excel and import that through a general table.
Then when you edit the general table Excel will come up to edit it in.
You can add columns through the edit parts list command, but I don't think you can add a totals row without using a suggestion like Cadmanto's.
