Summary :
The SAP Note outlines changes to the RFC connection for the SAPNet R/3 front-end system to enhance system availability. Updated code for Transaction OSS1 will redefine destinations for better stability when users modify technical settings. Applies for release levels above 6.40 (SAP_BASIS) or if corrections exist due to Support Package levels. Users might need to regenerate SAPOSS destination as described, without needing note implementation. Ensure to manually add specified IMPORT parameters to the EPS_UPDATE_RFC_DESTINATION function module via SE37 if corrections are manually implemented or using SNOTE.
Key words :
