The data reloading

Hi Experts,

I have DSO-ZDSO01 with the following data.

0MATERIAL 0CALDAY 0QUANTITY

A 01.02.2010 100

A 23.02.2010 120

A 04.03.2010 200

B 03.04.2010 300

B 23.03.2010 340

B 03.05.2010 200

I need to reload this data to another DSO-ZDSO02 (only 0MATERIAL is key field) and I would like to have the following data.

0MATERIAL 0CALDAY 0QUANTITY

A 04.03.2010 200

B 03.05.2011 200

Does anyone know how to do it?

Regards&thanks

Marek
