Dear Rao,
Thank you for confirmation.
By the way, my scenario is like this :
My company has bought several raw lands (has land certificate number). After develop those lands, then they split lands into small area and will be offered to tenant.
We create land (as commercial view) and rental object. Now we don't have relationship between raw land and usage view (land & RO). The requirement is we need to record land certificate number in rental object.
If we can use parcel of land, we will treat this parcel as raw land to keep information about certificate number and then assign it to RO.
Thank you,
Budi
