15.3 Bottom-Up Development
So-called bottom-up development (Figure 15.7) involves creating your artifacts
(view and stored procedures) directly in the SAP HANA development environment
and then making those SAP HANA artifacts available to the ABAP environment.

Figure 15.7 Bottom-Up Development
As mentioned earlier, bottom-up development has been superseded by top-down
development, which was discussed in de tail in Section 15.2). SAP recommends
top-down development if you’re on a re lease that supports it (ABAP 7.4 SP 5).
Nonetheless, you may be in the uncomfortable position of being between 7.4 SP
2 (in which bottom-up development was fi rst enabled) and SP 5 (in which topdown
development was enabled), with no prospect of moving to a higher support
stack for some time. In addition, SAP warn s that there may still be situations in
which a top-down approach doesn’t do what you require and thus you’re forced
down the bottom-up path, although such gaps are reduced with every support
stack released. Therefore, this section will talk a bit about how the bottom-up
approach works.
As you can see in Figure 15.7, there are three boxes (related to views, stored procedures,
and transports) that together make up the bottom-up approach. This
section discusses each of these boxes in turn. Section 15.3.1 talks about how to
