Delta DTP possible in BW 7.3 from source InfoObject to a target InfoObject?

Hello,

I have two customized master data.

I want to load from master data InfoObject X to master data InfoObject Y in BW 7.3 via a delta DTP due to huge number of records, is it possible?

Everytime i try creating a DTP it automatically creates a FULL DTP and no option to convert it into a delta one.

I understand there is no changelog/timestamping for an InfoObject but nothing new with BW 7.3 yet to load delta from InfoObjects?

Regards

Nidhi
