If no action is taken for a longer period and the beas-function is not available any more in the SAP environment, the SAP screen saver could probably be the reason.
This can be set up under
SAP Administration - System initialization - General settings - "Services" tab under "Screen-off time" (min.)
If necessary, set large times such as 999 minutes.
Inactivity while printing
If beas fails to respond when printing reports, it could be due to the fact that the reports are not stored locally on the computer.
Please try to store the reports locally on the computer. If the error is still not fixed, please contact Support.
