Summary :
SAP Note highlights that users of the Extended Warehouse Management (EWM) system are experiencing poor performance, specifically reporting long dialog response times and high system resource consumption. Key trouble areas include small transactions like radio frequency (RF) transactions and large transactions such as the release of large wave picks, affecting both CPU utilization and database size. The root causes identified include the use of CPUs with inadequate single computing unit (SCU) performance and poor maintenance of databases and NetWeaver components. Additionally, inadequate execution of periodic tasks outlined in SAP EWM guides and non-implementation of relevant SAP notes in the "P" (performance) category contribute to the issues. Recommendations involve using CPUs that meet the specified SCU performance criteria, maintaining databases, conducting recommended periodic tasks, and applying all relevant SAP notes to optimize performance strictly.
