Extracting ST03N / DB02 from R/3 to BW

Hi Gurus,

For a new project we are examining how to get ST03N / DB02 data from R/3 into BW.

From what I've learnt so far, the data isn't that easily to fetch...

Is there any standard business content for this?

For ST03N I found a function SWNC_COLLECTOR_GET_AGGREGATES and for DB02 i found table MSQSNAP.

This means we would have to write generic datasources to fetch data.

Is this the way to go or are there any other options?

Thanks in advance...
