Summary :
In scenarios with excessive workflow initiation, ERP systems may encounter performance slowdowns, notably impacting dialog users. The root cause typically relates to resource allocation inconsistencies between workflow processing and dialog or RFC actions. Parallel processing of workflows through event triggers compounds this, generating numerous transactional RFCs (tRFCs). SAP recommends several methods for managing system load effectively. These include modifying settings in SMQS QOut Scheduler to limit dialog work processes used by workflows, reallocating workflow processes to dedicated RFC servers utilizing RZ12 adjustments, and configuring RFC destinations to optimize load handling. These actions help stabilize system response and facilitate efficient workflow execution.
