Summary :
The SAP Note addresses system overload due to excessive parallel connections or single-process server programs, leading to frequent "timeout during allocate" errors in R/3 gateway. To manage this, from qRFC Version 6.10.042 onwards, it allows the limitation of parallel tRFC/qRFC connections to a specific destination via the qOUT Scheduler. This functionality is essential for systems with limited process capabilities such as warehouse management systems or external server setups. Configuration is done through the qOUT Scheduler Monitor (SMQS), and comprehensive documentation on setting up and monitoring is included in an attached PDF.
Key words :
terms load limit, individual monitoring screens, external server programs, business connector connection, qout scheduler monitor, warehouse management system, warehouse management, business connector, qout scheduler, server program
