Once the Value help view is created and released then go back to Fiori “DDIC Extensibility Group”. Refer blog: Create CDS Value Help or F4 help for In App Field Custom Fields | SAP Blogs

Open the tile Custom Fields or Custom Fields and Logic

Then click on the " + "symbol to create.

Here we will add custom field in Purchase Order Header screen.

Select Businesses Context "Procurement: Purchasing Document"

Label "Country of Destination". (Any label as per business need)

Identifier auto populated (you can edit but starts with ZZ1_ or YY1_)

Tooltip Auto populated

Type "Code List based on CDS View" (As per this blog we used CDS view. There are many more other options.)

Value Help View Select Help View name.

Then click on Create / Create and Edit.

Once you click Create Custom Field will get created with Not Published Status.

Go inside the field and open tab section UIs and Reports for maintaining where it can be shown in screen. Click on the “Enable Usage” button against following options as per image. This will mean that the new field is now enabled to be used on this UI. Once you click “Enable usage”, the field usage column will be changed to “Enabled”.

Click on “Save” button to save the changes

The field is now saved but for changes to take effect and the field to be available for addition in the UI, it needs to be published. Click on the “Publish” button to publish the field.

It will start updating its status as Publishing. This process may take few minutes.

Once process is complete like adding custom field into table and UI it will be changed to status Published. Which means it is okay for testing or delivery.

  Then go back to Home->Purchasing - Purchase Order Processing->Manage Purchase Orders

Open any existing PO you can see Custom fields tab and your added field with f4 option.

click and check F4 button


Select ok and save entry.

In conclusion I can say that the whole process is very simple just follow the steps. Please let me know your hurdles on the this. This process will help you create many more Value Help in different application areas with In-App extensibility in BTP area i.e., may be On-premises or Cloud.

I will add few more Value Help options in other blogs how to add F4 in other ways as well.

Please feel free to ask any sort of doubt. Thanks to all. Enjoy!!!...



People who attended SAP Inside Track event at Kolkata on 17th June 2023 should also read this blog on BTP. I will also come up with another blog on RAP which I presented there. This event was organized by moumitasaha.thedatatherapist(LN), Pradipto Kumar SahaSandeep Mukherjee, & SUBHASREE GHOSH with the support of many volunteers (check this post) and sponsors like IBM and others. Needless to say, this was another successful SAP Inside Track event in India with around 600 sap community members attending 28+ sessions. Thanks to all for making our dream a success.
