Unable to increase the number of background processes, Plz guide

Hi,

I recently installed SAP NetWeaver 2004s ABAP Trial Version.

When I go to TCode RZ10 when I do Import Profiles of Active Servers, then in the Display Profile Check Log I get the following error message:

"Instance DVEBMGS00 for system NSP not configured"

I tried restarting the server, again doing the import but nothing helped.

I also did the whole install again but still the same error.

System works normal, but I want to increase the number of background process. Due to above I am unable to save the changes made in the instance profile.

Any tips on the above issue or workaround to increase the number of background processes.

Thanks,

sam
