Re: Want change material base unit

you can change the base unit of measure :

• If there are no stocks of the material in the current period and in the
  previous period

If there are stocks in the previous period, you can clear them as
follows:

a) Post the stock in the previous period to the current period (for example,
using movement type 561) so that the stock for the previous period is the same
as the stock for the current period.

b) Clear the stock with the posting date in the previous period (for
example, using movement type 562).

• If no purchase requisitions, purchase orders, or scheduling agreements exist
  for the material
