SAP server busy

michaeloneil — Thu, 21 Apr 2022 11:09:00 GMT

Hi all

I have an unusual issue in SAP with one of my automations that I've never seen before and hoping someone on here might have the solution. I am running a transaction that uploads files to SAP and sometimes I get the below error message and when this appears the application is frozen. I cant interact at all and have to kill SAP using task manager I've tried a few things around wait periods in case the process is running too fast and I've even tried using sap scripting to perform the actions in a code stage to hopefully resolve it but no luck.

Has anyone seen this before and know of a solution? Restarting the application doesnt work as the error might just come up again so its very difficult to predict and build a mitigating solution for it.

Hi, Michael,

this is due to filling some "SAP Cache" and that's why SAP triggers this message. That is what I concluded seeing this at several clients. So someone with SAP experience can explain it in a better way.

There are two solutions to this:
1. decrease the frequency you load the files into SAP so that it can cope with all the data you are uploading. We empirically realized that the activity which we were doing (also uploading files) could cope with 10 files in one run. Then we stopped the process, logged out of SAP, closed SAP completely (saplogon) and then started again. This resolved the issue.
2. spy this window but not in SAP spying mode but Win32 or AA and when it appears handle it via clicking on Retry then wait 10 s, again click Retry (if the window still exists) until it disappears.

Hope this helps.

Regards

Zdenek

Hi @Zdeněk Kabátek

I was thinking it was some kind of caching issue but I wasnt sure why since this frequently happens on the first case to be uploaded. I've worked around a solution using SAP scripting to more effectively do the upload actions and added in several sleep stages before and after uploads to allow sap to "catch up" which appears to be working. For the warning message I wasnt able to spy the window since the process and SAP freeze up and when manually clicking the retry the window never seems to disappear.

Thanks for your explanation of the caching it helped me understand the issue better.
