Field Extensibility in S/4HANA Cloud


# Extensibility Overview

With the Extensibility apps, you can create custom fields, data source extensions, and implementation descriptions for specific business contexts to enhance pre- delivered applications that are extensible to adapt them to your business needs.

You can also create custom CDS views based on pre- delivered data sources. The data of an application is distributed across several database tables. Using CDS views, you can merge the data from different data sources and rearrange the table fields according to application-specific needs.

You can create custom business objects with UIs. You can also add custom logic to custom business objects. You can thus create your own applications based on custom business objects.

You can use Custom Analytical Queries to create new queries or reuse predefined queries. You use fields from CDS views to create a query.

Extension items can be transported with the apps Export Software Collection and Import Software Collection to be productively available und usable.


Nate: You can extend applications and their UIs, reports, email templates, and form templates only if the applications that you want to extend are extensible.


# How to Check if Fiori App is extensible or not

Go to Fiori App Library (

And check if ‘Create Customer Project’ App is extensible or not. We would use ‘Create Customer Project’ App for our example for this article.

This app is extensible


# Add custom field in Create Customer Project App

We would add a field (Project Type field drop down values) in app ‘Create Customer Project’.

Business Unit:     Mining

Consumer Product


Step 1: Go to ‘Custom Fields and Logic’ App

Click +

Note: You need to select right Business Context from drop down

Click Create & Edit

Enable wherever field is required, also make it searchable

Got Published (Field is available to be consumed)


Step 2: Go to ‘Create Customer Project’ App

Now you need to add that field which we created in previous step.

Click User Icon

Click Adapt UI

Right Click on the page and Click Create Group

Name This group as “Customer Specific Fields”

Right Click on Customer Specific Fields and you would get options – Select Add Fields


Search your fields i.e. Business Unit

Select and click OK

Click Publish and then Save Exit

Now the field is available in ‘Create Customer Project’ App with drop down options

Step 3: Go to ‘Create Customer Project’ App and create project with using custom added field


Similarly, you need to add this field in Plan Customer Project App so see these fields there.

      Hi Shakeel,


      Very nice explanation, thank you.

      I wonder that, can we use this custom field on customer project on our reports(Project Profitability, market segment etc.)?

      When I check attributes feautures of "Project" , I could not find this custom field.

      Do we have to populate on market segment as a characteristic?


      Kind Regards,

      thank you for the blog.


      i have couple of questions - can you please clarify. i am on S/4 HANA 2020 on premise.

      1. how do we identify the technical object associated to business context here ?

             2. Can we add data elements from data base rather than generic texts

      3. even though i have enabled key values to be displayed in personalize option, i could not see               key values




      Thank You
