Difference between COPA and BW
I want to know what are the difference between COPA and BW. Some one already implemented COPA for our client and now the client is asking what are the advantages of implementing of BW and Why they are going for BW? Because already COPA was already implemented.

BW is a business warehouse of OLAP-type for SAP. BW has several standard 'cubes' for every component in SAP; GL, FM, etc. Amongst them there is also CO-PA. CO-PA by itself is sort of OLAP-cube, so putting it to BW could be only from technical reasons (perfomance, for example) or customer-specific definitions. In BW, like every modern OLAP tool, you can build your own cubes, merge several cubes, define additional key figures, build sophisticated reports, etc. Thus, it's more powerful tool in terms of BI analysis. Therefore, situation where you need BW only for CO-PA is possible and potentially justified.
