Hi Zdenek,
I think I've got an idea how you can solve this issue.
Let's say your instance have 3 SAP Servers (CI/AS), A, B and C. Let's assume you will schedule your job on a fixed destination, server A. And I assume you know how long this job should run approximately, let's say 2 hours and the scheduled time is daily at 21:00.
What you should do:
- Create a "special, daily" Operation Mode for servers B & C, which make sure that daily between 20:30-23:30 (slightly more than those 2 hours jobs as an example, or less, up to you) on these servers there will be NO DIALOG workprocess running. You can set them to background workprocess for example. After that it will switch to "normal/existing" Operation Mode.
This will make sure that during the job running-time, there is only 1 server (A) who has DIA-workprocess, and this is where the job itself is running at that time.
I hope this will help you.
Regards,
Andre
