!! This processing can only be carried out as background processing !!

What causes this issue?

You have requested a function for the processing of bulk data. This
function leads to a drain on the system and has a negative effect on
response time. In order to prevent waiting times from becoming too
long, this processing is only possible as background processing.

System Response

Processing is terminated.

How to fix this error?

You should request all bulk processing in the form of background
processing. In particular, bulk processing that changes data can only
be carried out in the background. Please start the program with a
selection version as background processing (<LS>Program -> Execute in
background</>).
