Certain things in the SAP system must be set up for access to JCo. The first order of business is a valid username and password that the Java program needs to connect to SAP. The username has to have certain authentications in SAP. The authorization objects needed are S_RFC, ACTVT:16, and FUGR. Table 32.3 contains all the function groups needed, based on the SAP system release that's running.
SAP Release | Function Groups |
---|---|
3.1H and greater | RFC1, SG00, SRFC, SUNI, SYST |
4.0A and greater | RFC1, SDIF, SG00, SRFC, SUNI, SYST, SYSU |
4.6A and greater | RFC1, SDIF, SG00, SRFC, SYST, SYSU |
4.6D and greater | RFC1, SDIFRUNTIME, SG00, SRFC, SUNI, SYST |
If the preceding settings are unfamiliar to you, don't fret. An SAP basis administrator for your system will set up the system correctly if she has this information.
