Figure 2.1: LSA example
LSA is a robust and valuable design, but it can be expensive to design, implement, and
maintain, both from a development perspective and from a database volume perspective.
In addition, the fact that there are multiple data staging layers introduces latency in moving
data from the acquisition layer to the report and visualization layers, thus delaying con-
sumption of data by end users.
With SAP BW 7.4 on HANA, the LSA architecture is replaced with LSA++. Recommen-
ded for SAP HANA only, LSA++ is an updated design and architecture standard which can
be used to simplify your EDW architecture. See Figure 2.2 for an example of the LSA++
architecture.
