Re: Doubt on OLAP Business layer

Hi

while creating universe you have two options to select the connections

1. OLAP Connection
2. Relational Connection

As per your requirement you have chosen OLAP Connection i think.

So OLAP connections to connect to an SAP NetWeaver BW data source based on a BW server, a cube, and a BEx query.

If your backed as BW ...then No business layer or universe is required to access BEx queries. We can directly select the BEx query as a data source.

You can do all the calculations & data restriction (CKF, RKF, Filters and Variables) and use Bex Q as direct source.

Please find the below link. To know the difference b/w OLAP and Relational connections and what are the advantages using the OLAP connection.

SAP BW is an OLAP vs. Relation connection
