Hi Team, We are trying to identify and associate flag to a particular activity based on whether there were some other set of activities post it or not till the next instance of the activity. So for example we want to associate a flag to Activity A if in a case journey activity B, C, D or E are occuring any time between the next occurence of Activity A within the case. We intend to track this for each instance of activity A taking place within a case and associate a flag whether the activities B,C, D or E took place or not in an OLAP table. We are looking for any way in which we can set the scope from the instance of activity A taking place till its next instance and check within this scope whether the other activities took place. Thanks in Advance. Soham Potdar

Hi @Soham_Potdar, thanks for reaching out! In the following, I will explain you one way to solve this problem. We will create the following OLAP Table: image785257 6.32 KB
  1. _CASE_KEY: Add the case key as a dimension:
_CEL_P2P_ACTIVITIES_EN."_CASE_KEY"
  1. condition: As a first KPI, we want to add the flagging or not flagging condition. This is the hard part of the problem. In the case below, I have chosen the activity Change Quantity to be your Activity A. You can simply substitute the PQL code with your desired Activity A.
*CASE WHEN * MATCH_PROCESS(NODE[Change Quantity] as src,NODE[Change Quantity] as trg CONNECTED BY EVENTUALLY [ src, trg ]) = 1 AND MATCH_PROCESS(NODE[Change Quantity] as src,NODE[Change Quantity] as trg CONNECTED BY DIRECT [ src, trg ]) = 0 *AND * CALC_REWORK("_CEL_P2P_ACTIVITIES_EN".ACTIVITY_EN = Change Quantity) >= 2 THEN flag *ELSE no flag * END explanation of this KPI: We want to flag a row in the OLAP table if the Activity A is followed by another instance of the Activity A (in the process flow of one CASE ID), BUT Activity A is not directly followed by another instance of Activity A (which means that we have at least one other activity like B,C,D,E in between them), AND there are at least two instances of the Activity A for one CASE ID. If this is correct, then we apply a FLAG, if not then we apply NO FLAG.
  1. Activity: Next, we want to add a KPI simply in form of an activity. This is the third column in our OLAP table:
_CEL_P2P_ACTIVITIES_EN.ACTIVITY_EN
  1. lagged activity: Last, we add the respective successor activity to every activity displayed in the third column. Simply add a KPI stating:
ACTIVITY_LEAD ( _CEL_P2P_ACTIVITIES_EN.ACTIVITY_EN ) The table is done. We can now filter on specific CASE IDs that are flagged. Extras: We can also add conditional formatting. Lets stick to the example above. Our target Activity A is still Change Quantity. In the OLAP settings, we can choose to mark all Change Quantity activities in the third column e.g. yellow background. If we now filter on a specific CASE ID, we see that the fifth and seventh (last) activity in the process flow of this CASE ID was the Activity Change Quantity: image811356 21.6 KB Last, we can add a process explorer to the analysis sheet to have a visually perfect overview of the process flow of the case: image654550 23.5 KB From this we can easily see that the Quantity was changed once, then the invoice was booked and then the quantity was changed again. I hope this procedure solves your problem! Best, Your Celonis Team
