Hi Preddy R,
now you are mixing a lot of topics also from other SDN threads.
The topics seem to be:
- - When are cells in the result set of a query input-ready?
- - What is NO2 aggregation?
- - What is disaggregation?
All three topics are explained in the documentation, inculding examples. Use your favorite search engine (e.g. restricted to help.sap.com) to find it. All these topics are very basic and to fulfil customer requirements one has to combine these features in the 'right' way. This is what consultants have to do, it is not the purpose of an SDN thread to provide ready to use solutions for customer projects.
Having read the above mentioned note you should be able to answer why disaggregation may fail. The most elementary reason is that there is no data to disaggregate to and you say your planning cube is empty. The question is not why disaggregation fails but why should it work? What does it mean to disaggregate a value to an empty set (of records)?
This topic also indicates that you should think about the data model of the application, the amount of planning data to be created, etc.
Regards,
Gregor
