Hi,
We are on SAP BW 7.3 SP09 and Sybase IQ NLS.
My question relates to the creation of the DAPs in SAP BW.
I am aware of the Semantic Keys in DTPs and how they work and when one should use them as well as the benefits.
In DAPs we also have a tab called Semantic Groups. I have read the standard description which effectively tells me that the data is stored based on the semantic grouping in Sybase IQ.
My question is when and why would use this? As the DB has more work to do to read and sort data. I know i dont have to but want to ensure that I not missing any major benefit in not using them.
How is the grouped data used for read purposes?
Thanks
