ABAP_RFC , Remote Function Call in ABAP Release 4.0 ITOC
ABAP_MODIFICATION_NN WAIT Statement
WAIT $[UNTIL condition$] UP TO time SECONDS The statement WAIT makes it possible to wait for a response from a function module called asynchronously. This requires the addition PERFORMING form ON END OF TASK. WAIT must be executed in the same ABAP_ISESS .
ABAP_MODIFICATION_NN RECEIVE Statement
RECEIVE RESULTS FROM FUNCTION func KEEPING TASK The KEEPING TASK addition preserves the remote context in the subroutine for reuse.
ABAP_MODIFICATION_NN Error Messages from the Remote System
If an error occurs in the target system in RFC, details of the error message are passed to the calling system (SY-MSGNO, SY-MSGID, SY-MSGTY, SY-MSGV1, SY-MSGV2, SY-MSGV3 , and SY-MSGV4). These fields are set to initial in each RFC call.
ABAP_MODIFICATION_NN Load Checks for Asynchronous RFC
For each RFC destination, an improved load check is performed for asynchronous RFCs (menu path Destination - >ARFC Options in the RFC destination maintenance screen in AS ABAP). Before the function module is executed, the system makes sure that the target host has enough resources. If the host is overloaded, the execution of the function module is delayed (internally) for a short time. The algorithm used to determine the load situation on the target machine is the same used in asynchronous RFC with the addition DESTINATION IN GROUP. Be aware that this option can only be used for target hosts from ABAP_RELEASE 3.1H.
ABAP_MODIFICATION_NN <(>SNC<)> Option Maintenance for RFC Destinations
It is possible to define security options for each RFC destination. This is also possible for RFC Secure Network Communication. The SNC component (Secure Network Communications) provides added protection, for example by encrypting data transfers and applying secure mutual authorization between communication partners. To use SNC, an external security product must be installed and entered in the profile (see, for example, parameter snc/enable). If SNC is used, it is possible to specify whether additional protection functions are used for this destination in the SNC Mode setting. If this is the case, additional SNC options must be defined in the menu bar: Destination -> SNC Options.
ABAP_MODIFICATION_NN RFC Clients as Trusted Systems
An RFC client that is registered as a trusted system can log on to the RFC server without a password. Trusted systems must be defined in the trusting system (the RFC server) using the transaction SMT1. In the trusted system, the transaction code SMT2 can be used to define which systems act as trusting systems.
ABAP_MODIFICATION_NN Authorization Check
If RFC communication takes place within a single system and in the same user context (with the same client and user name), no RFC authorization check based on function pools (using the authorization object S_RFC ) is performed. More information about this topic can be found in RFC Authorizations.
