Summary :
With the release of SCM4.1, SAP offers new capabilities for parallel processing in Demand Planning (DP) mass processing. The update introduces internal parallel processing automatically managed by the system, enhancing the traditional method by employing asynchronous RFC calls for processing blocks of characteristics combinations. Adjustments are made via parallel processing profiles where block size and number of processes can be tailored, optimizing run times and system load. Prerequisites like sufficient dialog work processes and controlled server group usage in RZ12 are essential. Users must experiment with settings—particularly block size to balance process loads effectively. Monitoring transactions SM50 and SM37 are recommended for fine-tuning.
Key words :
background process simultaneously prepares, background process uselessly waits, additional 'external' parallel processing, normal background work process, background work process starts, dp batch runs, experience memory problems, create server groups, extremely system-dependent, external parallel processing
