When I try to mine a process from an event log I see wrong activity in the beginning. And can't understand why is it there. As well, BPMN model is built incorrectly. I can modify it, but I don't see it in process or variant explorer in a modified way.

 

I use Python simulation to generate data. it simulates facility with several rooms where users can move and drink coffee. Coffee increases their heart rate. As well, the system starts displaying messages and offers users to drink water.

 

In the process model I get users have increased heart rate in the beginning and their moves between facilities are happening in one direction, while in reality they move randomly.

 

I try to understand what do I need to modify (Python code for data generation or something inside Celonis) in order to see the real model and a sphagetti diagram showing all possible users' movements and events. Screenshot 2023-11-09 at 21.12.38 

 

Hmmm.... I would check the dataset. It is odd so many "loops" where a case is "stuck"in the same activity several times....

 

 

I'd review the iimestamps in the original event log (before ingestion)

  • Are they with time or only with date?
    • Are the original timestamp aligned with what you see in the process explorer (i.e. the first activity is always "Increased heart rate"?

 

It looks like you are having only date in eventtime, maybe you lose it during the SQL transformations.

 

If the above doesn't get you a solution, use CASE EXPLORER to follow in detail each case

 

Best luck!


As suggested. You might have overlapping timestamps. If all of them happened with the same timestamp they might be showing weird results.

 

Additionally What you have here is a generated dataset so I would also check your generation methods.

 

I'd recommend taking a case and looking it up in the activity table to check the raw data for irregularities. There is also a possibility that couple of cases have duplicated activities (or some cases are joined together) netting results with activities happening all over the timeset.
