Summary :
The SAP Note highlights enhancements and a workaround in the SGEN transaction used for ABAP load generation. Enhancement updates in Support Packages facilitate delayed load generation, using transaction SGEN to select generation tasks and application servers for parallel processing but not immediately initiating the load. For a later start, do not trigger 'Start Job' in the “SAP Load Generator - Job Monitor” screen. Instead, use transaction SE38 to execute 'RSPARAGENER8' in the background, create a job variant with GEN_TASK set to '0', and schedule the job for one-time execution at a preferred time.
Key words :
'sap load generator - job monitor' screen appears, 'sap load generator - job monitor' screen, load generator status shows, additional key words sgen, job monitor screen, release / support package level, screen 'execute report, choose 'start job', support package level, scheduled generation job
