From the Administration Perspective - Client shows a higher number of activities - However while checking the Process Monitoring the number of Activities shown are much less.
Release : 12.x
Component : Automation Engine
Functional Area : AWI
This is as per design - The list displays records according to the specified filter settings in UC_SYSTEM_SETTINGS > COMBINED_ACTIVITIES_LIMIT. If the process monitoring search result returns more tasks than the value entered here, the system indicates + on the list, next to the value defined [Example: 500+ ].
This is why you may run into scenarios where the number of activities in the client are higher, whilst the process monitoring perspective show you 500+.
You can increase this value in the UC_SYSTEM_SETTINGS variable on client 0.
If there is no entry in the variable - It means that the default value of 500 is being used - You can manually add the COMBINED_ACTIVITIES_LIMIT Key and specify the limit you would like to have on the Value1 column.
However the recommended best practice would be to not have a very high number - This would have an impact on the Automation Engine Performance.
You should regularly housekeep your Process Monitoring perspective and also carry out the recommended DB maintenance procedures.
