Listing 14.1 Data Declarations in the Root Class
You have a place for the data to live, but how does the data get there in the first
place? Surely, you have to go to the database at least once? Yes you do, and in
order to enable this you need yo ur root class to implement the IF_SHM_BUILD_
INSTANCE interface, which has the BUILD method. BUILD is called automatically by
the SAP system, but you cannot code the method until you’ve created the broker
class, so Section 14.2.2 will return to this topic.
In the meantime, you can define your own LOAD method (Figure 14.3) to transfer
the entire database table to an equivalent internal table.
