Change of Unit Of Measure

Hi,

İ have a material created in more than 20 plants two months ago. Since then, many material documents has been created and there is a considerable amount of stock both in the previous and current periods.

To change the UOM,

*i have to complete / mark as deleted all the documents related to the material.

• there must be no stock in the last two periods.

As this is hard work considering the number of plants, is there an easier way of changing the UOM?
