Hi All,
As I consider how to create BW models where HANA is the DB for a BW application, it makes sense moving the reporting target from Cubes to DSOs. Now the next logical progression of thought is that the DSO should store the lowest granularity of data(document level). So a consolidated data model that reports on cross functional data would combine sales, inventory and purchasing data all being stored at document level. In this scenario:
- Will a single report execution that requires data from all 3 DSOs use more memory vs the 3 DSOs aggregated say at site/day/material?
- Lower Granularity Data = Higher Memory Consumption per report execution
I'm thinking that more memory is required to aggregate the data in HANA before sending to BW. Is aggregation still necessary to manage execution memory usage?
