Hi,
My above statement was belongs to add info object only.
if you need historical data for added info object then delete and reloading data is mandate here.
if your bw 7.3 above then you can add info object to dso thru remodeling concepts.
at DSO - Data deletion was not mandate. because dso have overwrite properties. so we can reload historic data to dso without deleting data to fill added info object if all key fig have overwrite property.
Thanks
