Extensibility covers a broad spectrum of topics that allows customers and partners to adapt standard business software to their business needs. It ranges from business configuration; layout adaptation of user interface (UI), forms, and reports; custom fields and logic; integration; and custom terminology and translation to customer-specific applications. Extensibility in the SAP S/4HANA suite can be categorized into two main parts: side-by-side extensibility through SAP HANA Cloud Platform and in-app extensibility through built-in capabilities.

Business role:

This document will focus on demonstrating key user extensibility: how to consume the custom field in your custom CDS view and custom Analytical Queries.

In my demo to create custom fields, I am taking an example from “Customer Project” app. Using this app, I intend to bring a customer specific field that I could later consume it in my custom CDS view and can further be exposed as OData service or may be bring them into custom Analytical Query for further reporting capabilities.

Customer Project App without any custom Field

A simple way to identify if extension options are available for a particular app is the Fiori Apps Library

If the specific app indicates the extensibility of UI5 application in the front-end server, then the app is extensible.

Custom Fields

As a first step towards the creation of custom field, Go to Custom Fields and Logic Appà Fill the mandatory fields. Make sure the business context is selcted as ‘Engagement project’ and the custom Field I would like to add is Technolgy

Since I would like to have drop down option for the custom field- Technology I chose ‘Code List’ as Type under General Information and added values that include Artificial Intelligence, Big Data, Business Intelligence etc.

Now, under the tab strip UI and Reports, I will enable the appropriate data sources that are required while creating the custom CDS views. In order to identify what specific pre-defined views are available,  one need to make sure the data sources are explicitly selected from the cog wheel as shown in the figure below.

Now, I have published the custom field- Technology.

To bring this custom field- Technology into the specified app, Go to Create Customer project app and then follow the steps:

  1. click the user profile and select Adapt UI
  2. click UI Adaptation
  3. Select the Group Icon
  4. I renamed the group Icon to Custom Field my example as shown in the screenshot below.
  5. Right click on ‘Custom Field’ and select add field from the available fields, select ‘Technology’ as this is the custom Field I wanted to bring into this app.

Save and Exit

Customer Project App with custom Field

Fill the mandatory fields in there along with the new custom field you have added to validate how data gets populated for the reporting purpose.

Custom CDS view

Now, I will create a custom CDS view using I_EngagementProject as this was one of the data source enabled during the creation of custom field.

 

Custom CDS view name: YY1_Project_Sample and selected Analytical (described in the below section)as an option which could be later consumed in custom Analytical Query app.

Note: As of 1808 upgrade, we no longer will have the option to enable OData and Analytical(as a cube) at the same time while creating custom CDS view- SAP Note

Custom field- Technology will be available as selection field for the creation of custom field

I have additional fields added to make the reporting looks more meaningful, which is available on the right section of the above image.

Save Draft and Publish!

When previewing the newly created custom CDS view- yy1_project_sample, I will see the new custom field as well getting populated.

Custom Analytical Queries

 

Name the Query: YY1_Project_sample1 and select the Data Source, in this case it will be the custom CDS view that I just created.

Select YY1_Project_sample from the Data source section.

 

Note: While creating of custom CDS view, please make sure the analytical option is turned ON, otherwise, the same custom CDS view will not be available for creation of Custom Analytical Query.

You will notice all the fields that were part of selection in custom CDS view to reflect in the Custom Analytical Query as well. Here as well, you have the option to pick and choose the fields that are need for your reporting capabilities.

The selected fields will start reflecting in the right pane (just like custom CDS view)

In ‘Display’ option, there are several arithmetic operations that can be carried out as well.

Save the draft and Preview!

Drag and drop the fields in the ‘ROWS’ tab to better analyze the data. And you could see the custom field- Technology as well getting populated with the data that was entered for demo purpose.

In my next blog, I will be focusing on Fiori Apps that are not extensible however, we still could create custom fields and expose them in custom CDS view and build Custom Analytical Queries and many more with new extensibility features😉
