Plan Value in Proportion/Product Unit

Hi,

We have batch management activated in our system and we use Proportional/Product Units.

In the tab page Proportional/Product Units in Material Master, there is one field Plan Value.

Could any one tell me from which table I can get its value for a material. Also please share which all tables will get updated by using Proportional/Product Units functionality.

Thanks in advance.

Regards,

Pavan
