Hello community,
since four days offers SAP the new patchlevel 39 of the SAP NetWeaver RFC library. With the ID 128 is a new function inserted, against patchlevel 38, call RfcInstallBgRfcHandlers - it installs necessary callback functions for processing incoming bgRFC calls. You can find a detailed explanation in the sapnwrfc.h file.
Cheers
Stefan
