AutoIT script running fine in foreground but failing as scheduled job

[jdunlop]

I inherited an AutoIT script that has been running ok for years on an Windows XP pc.

It logs onto a SAP server and extracts data to a local file on the C: drive.

Recently I moved the script to a Windows 8.1 PC and found that although I can run the script manually and it works fine,

when it is added to a scheduler and run as a scheduled job, the code stops working and the program hangs.

I have tried everything I can think of including changing the "Send" commands to ControlSend commands.

I cannot figure out why the same code would work fine every time when run manually but when scheduled, it fails.

Anyone have any ideas about this?

Welcome to AutoIt and the forum!

As a scheduled job your script is being run with different credentials. So the problem you face might be caused by missing simple permissions.
Add as much error checking to your script and log all results to a log file.

Thanks for your reply, water.  Yes, I have done just that. I write to a logfile after every command and although I have now managed to get the script to complete, it doesn't execute correctly. It extracts data from a SAP database and creates a file on the C: drive but the file never gets created for some reason when run as a scheduled job. I understand that the job is run with different credentials but I can't see where Windows 8.1 would have the difference.

Hard to tell without having seen your script.

Solved it.  Thanks, water, you put me on the right track.  It turned out that the scheduler was running the job as a System task rather than a User task which was why the credentials were different.  I changed it to a User task and it works ok.  Thanks for your help.
