I need to segment data to confirm invalid data.
Conditions are as follows.
1）eventA = eventB + eventC
When eventB or eventC occurs, eventA is also occurs.
And then propA has eventID.
I would like to segment propA data when previous condition doesn't work.
I confirmed invalid data like this.
eventA occured, but eventB or eventC didn't occur.
How sholud I set the segment function?
