It is impossible to drag a unit of measurement from one group to another.

If you want to change the UOM name or its coefficient in relation to the base UOM:

  • Select the unit of measurement whose properties you want to change
  • Use the UOM properties item of the context menu or the Document > UOM properties main menu item
  • Make the necessary changes
  • Save the changes using the Document > Save document main menu item or the 
     button on the toolbar.

When changing the coefficient in the Units of measurement dictionary, the coefficients in goods cards using this UOM will not be recalculated.
