• What is the cause and solution for SAP error message XMS_ADM126 - Error scheduling message in qRFC ?

  The SAP error message XMS_ADM126 indicates an issue with scheduling a message in the qRFC (queued Remote Function Call) framework. This error typically arises when there are problems with the configuration or the environment that prevent the successful scheduling of messages.
  Causes:
  
  Configuration Issues: Incorrect settings in the qRFC configuration can lead to this error. This includes issues with the logical system, RFC destinations, or qRFC queue settings.
  Queue Locking: If the queue is locked or if there are issues with the queue's status, messages may not be scheduled properly.
  System Performance: High system load or performance issues can prevent the timely processing of messages.
  Authorization Issues: The user or system may lack the necessary authorizations to schedule messages in the qRFC.
  Network Issues: Problems with network connectivity between systems can also lead to scheduling failures.
  
  Solutions:
  
  Check Configuration: Review the qRFC configuration settings in transaction SMQ1 (for outbound queues) and SMQ2 (for inbound queues). Ensure that all settings are correct and that the logical systems and RFC destinations are properly configured.
  Monitor Queue Status: Use transaction SMQ1 and SMQ2 to check the status of the queues. Look for any locks or errors that may be preventing message scheduling.
  Check System Performance: Monitor system performance using transaction ST22 (dump analysis) and SM50 (process overview) to identify any bottlenecks or issues that may be affecting message processing.
  Review Authorizations: Ensure that the user or system has the necessary authorizations to perform qRFC operations. This can be checked in transaction SU53 or by reviewing the user roles.
  Network Connectivity: Verify that there are no network issues affecting communication between systems. This can be done by testing the RFC connection using transaction SM59.
