Validating KPIs for the object-centric Accounts Payable Starter Kit

In the Accounts Payable Starter Kit’s Knowledge Model, check that all the KPIs (key performance indicators) contain the correct business logic for your organization.

The main Knowledge Model for the Accounts Payable Starter Kit is “SK - Knowledge Model”, which is in the Starter Kit’s Knowledge Models folder. Work with this Knowledge Model to validate and change KPIs. “SK - Knowledge Model” points to the base Knowledge Model stored in the Celonis Marketplace, which you can’t update directly. Changes that you make to the PQL formulas, KPI names, or formatting in “SK - Knowledge Model” override the base Knowledge Model.

Each KPI in a Knowledge Model contains a PQL (Process Query Language) formula. Some KPIs are reused inside other KPIs as nested formulas. When you adjust the business logic in a single formula, and save it, the change is simultaneously reflected in all the KPIs that reuse the formula.

You work with Knowledge Models in Studio, and any changes you make are applied when you publish a new version of the Starter Kit. You’ll need Analyst permissions on Studio and the Knowledge Model to modify any of the KPIs and their calculations. If you need training, check out the training track “Build Knowledge Models and Views” on the Celonis Academy.

Here’s how to work with the KPIs in the Starter Kit’s Knowledge Model:

  1. In the Celonis navigation menu, select Studio.

  2. Find the Accounts Payable Starter Kit (object-centric) in your Studio space navigation.

  3. Expand the package’s structure using the arrow.

  4. Go to the Knowledge Models folder and select “SK - Knowledge Model”.

  5. Select the KPIs section of the Knowledge Model.

  6. You can sort and search the KPIs using their name or ID. The prefix to the ID shows what type of component they are. At the end of these instructions, we’ve noted the most important KPIs to check.

  7. To see and edit the full PQL formula and other settings for a KPI, click its row to open an editor. The editor automatically validates any changes that you make in the PQL formula.

  8. If you want a fuller-featured PQL editor that lets you select from the tables and columns in your data, click on the pen icon next to the PQL formula.

  9. If you need to disable a KPI or formula, click the three vertical dots at the top of the editor, and select Disable Scope, then click Disable to confirm. When you do this, the object can't be accessed or used anywhere in the package, including by other apps that depend on it.

  10. If you update the business logic for a KPI or the variables it uses, update the documentation for business users to reflect your changes. You can find the built-in documentation for your Starter Kit's KPIs in your Studio space navigation. It's in the folder Documentation > KPI Documentation.

  11. When you’ve made changes to the KPIs, use the Publish Package button at the top of the screen in your Studio space to publish a new version of the Accounts Payable Starter Kit.


For the Accounts Payable Starter Kit, you can manage the settings for most of the important KPIs using the Validation Cockpit and the Settings view. Two important KPIs that you can only manage in the Knowledge Model are:

  • Relevant Invoices - KPI ID AP_Dimension_VendorAccountCreditItem_INDICATOR_GenericValidationClearedDocuments

  • Relevant Credit Memos - KPI ID AP_Dimension_VendorAccountDebitItem_INDICATOR_GenericValidationOpenAndClearedDocuments

These two formulas are used in many other KPIs to exclude irrelevant documents.

The Knowledge Model variable “Reference Date” (with the ID AP_Variable_Input_CurrentDate) is relevant if you are analyzing a one-time extract of data taken in the past. The default setting is TODAY(), but if you set a fixed date on which the data extract was made, KPIs are calculated as if that date were today. That means you won’t see incorrect results due to including the days since the data extract and overaging the credit memos.
