Chapter 3 Summary © SAP AG l RFC allows you to implement program-to-program communication between R/3 systems, R/2 systems, and external systems. In SAP systems, you set up the connection with ABAP/4. For external programs, you use the relevant RFC libraries. l There are several RFC variants (synchronous, asynchronous, and transactional). l In R/3, you maintain connection parameters in the table RFCDES. l From R/3, you can generate external RFC programs.
Exercise for Chapter 3 Report name: ZBCE##C1 Function group: ZE## Function module: Z_BC415_##_... Logical destination: BC415_## ##: Group number Implement an RFC communication between two R/3 systems to read data (airline carrier information) from a server system and output it in the client system. Proceed as follows: 1. Create a function group (see above) in a server system to be specified by the instructor. 2. Program a function module assigned to this function group (see above) and including the following functionality: • Import parameter for the airline carrier • Table parameter for selected records of table SCARR • Exception for an invalid key evaluation Use the following program fragment to allow generic selection in table SCARR: IF NE SPACE. TRANSLATE USING '+_*%'. ELSE. = '%'. ENDIF. • Read the table SCARR and transfer the valid records to the internal table.
