Summary :
This SAP Note addresses a dump error with the message "CALL_FUNCTION_OPEN_ERROR" occurring within ABAP/4 program "SAPLOLEA" due to protocol issues with SAP GUI. The root causes include transactional RFC processing errors following a program correction at kernel patch level 944 in Release 4.6D, dialog disruption by the "Maximum number of sessions reached," and dumps in non-SAP GUI environments. The resolution involves upgrading to kernel patch level 956, modifying the function module GUI_IS_AVAILABLE, and implementing corrective measures and exceptions as referenced in Notes 710920 and 1244208, besides analyzing application-specific causes.
