What does it do? The additions EXPORTING and IMPORTING assign the actual parameters a1, a2 to the input and output parameters defined in the database procedure. This method of passing parameters can be used in both static and dynamic calls. The proxy parameters p1, p2, ... to which the actual procedure parameters are assigned in the mapping of the database procedure proxies are specified after the additions. The data types of the actual parameters can be determined by referencing the type declarations of the associated database procedure interfaces. The read positions are general expression positions.
