Copy Previous Value to Blank Period by RUNNING_SUM and RANGE_APPEND functions

 Posted on 2021-10-30  |  2 minutes  |  380 words  |  Kazuhiko Takata

At Investigate Workload Trend of Cropped Subprocess I showed trend of activity count, and at that time I used RANGE_APPEND to fill zero count in trend graph. Today I would like to use different aggregation RUNNING_SUM and fill value to blank period. Imagine you would like to check weekly trend of credit amount regarding some customer. Credit amount is increased by the amount of net value when ‘Receive Order’ happened, and it is decreased when ‘Clear Invoice’ happened. [Read More]

Create Key Column of Activity Table

 Posted on 2021-10-23  |  3 minutes  |  460 words  |  Kazuhiko Takata

Celonis Data Model always require unique key in case tabel (case key) to group activities belong to each case. How about activity table ? Activity table do not have explicit key column, instead combination of case key, activity name, timestamp, and sorting number are similar to activity key (those four columns are configured in Data Model). This week I was asked to create activity table key column due to duplication check purpose. [Read More]

Investigate Workload Trend of Cropped Subprocess

 Posted on 2021-10-16  |  2 minutes  |  383 words  |  Kazuhiko Takata

Celonis Activity record is good to investigate user workload, so you may already implement analysis to do this. Today I would like to crop activities to minimum subprocess then investigate workload against subprocess. Today’s output image is below. I set filter button of company code, also set three buttons to point out activities to crop subprocess pass through these activities. Right side Process Explorer is to check subprocess, in this case it is starting from ‘Approve Credit Check’ until ‘Cancel Order’ via ‘Deny Credit Check’. [Read More]

Group similar cases by Clustering

 Posted on 2021-10-02  |  2 minutes  |  397 words  |  Kazuhiko Takata

Last week I posted Convert Quantitative value to Categorical one by Quantile Function to create categorical dimension. Today I will create categorical dimension via different way, clustering. Clustering is one of the unsupervised learning method, to automatically group cases by their attributes. Celonis PQL has clustering funciton KMEANS, so you are ready to use clustering. Today I will use O2C process and would like to group customers by (1) their lead time from Invoice send to Clear Invoice and (2) net value. [Read More]

Convert Quantitative value to Categorical one by Quantile Function

 Posted on 2021-09-25  |  3 minutes  |  429 words  |  Kazuhiko Takata

Last week I posted Integrate Button Dropdown Entries to one Formula and integrated multiple dimensions. At that time I used string column that enable you to categorize each case, that is called categorical variable. In contrast quantitative variable such as order quantity, net value is not normally possible to use for dimension. If you would like to use these column as dimension, you need to convert its value to categorical value. [Read More]

Integrate Button Dropdown Entries to one Formula

 Posted on 2021-09-18  |  4 minutes  |  660 words  |  Kazuhiko Takata

I usually use two types of analysis components, time scale graph and drilldown table for my development projects. These compnents makes it possible to discover root cause of target KPIs by changing time scale or drilldown dimension. In the end, these components and attaching button dropdown were maintained many times, but I was annoyed to set variable value (especially long PQL) to each button entry (it was also cause of defects against my analysis sheet).

Use BIND function to enable multiple DOMAIN_TABLE

 Posted on 2021-09-11  |  3 minutes  |  520 words  |  Kazuhiko Takata

Variant Explorer is the major Celonis Analytical view to find process pattern by GUI operation. Of course I used it many times and enjoyed it at first, and found that I had a lot of effort to filter on and off to observe process. Today I would like to create collective list of variant to see major process KPI. Also I would like to show you BIND function that is difficult to understand but quite convenient if you know it.

Convert count unit of KPI by COUNT DISTINCT

 Posted on 2021-09-04  |  3 minutes  |  430 words  |  Kazuhiko Takata

Last week I was asked to convert count unit of some KPI (that returns 1 or 0) from delivery item to delivery document (convert if all items in the document are 1 then document KPI is 1, else 0). In this case delivery document and item columns are stored at Activity table like this post’s third topic. I already used DOMAIN_TABLE to group activity record by delivery item then calculate KPI.

Count rows of Tables in various way

 Posted on 2021-08-28  |  2 minutes  |  425 words  |  Kazuhiko Takata

Counting rows of tables is frequently used so we are not aware about how to do it. But sometimes I got stuck to do it so I would like to deep dive this topic today. For this demo case I use P2P data model and three tables, header EKKO (key columns are MANDT/EBELN), item EKPO (MANDT/EBELN/EBELP) and activity. Also I used sum of item Net value. Below screen is the result of this demo. [Read More]

Make Conditional Function to return 1 or NULL

 Posted on 2021-08-21  |  3 minutes  |  427 words  |  Kazuhiko Takata

Previously I posted Handle NULL efficiently in Aggregation Function and discussed how to unite formula of COUNT, SUM, AVG functions. Today I will create boolean function and use it for conditional aggregation. Imagine you would like to calculate net value of Sales Order (VBAP.NETWR_CONVERTED) in O2C process, but there are some conditons to calculate it. First condition is that sales order is active, means rejection reason column (VBAP.ABGRU) is not set. [Read More]
