Summary :
The SAP Note discusses executing R3up in AS/400 environments without requiring a local or interactive job. It allows remote initiation of R3up, mitigating WAN reliance and avoiding network disruption impacts in LAN settings. It details creating and modifying input and output files via CL commands (like UPDDTA and DSPPFM) to manage R3up communications, highlighting the importance of duplicating the first input entry in batch mode to compensate for an initial skip. The note provides detailed CL program examples for SAP Releases before and after 6.20, including adjustments for batch operations and file handling in AS/400.
