SAP ABAP Central: SAP S/4 HANA Custom Fiori app for Project & WBS using CDS View Table Function, SmartFilter & Tree table

In this blog, I would like to present the custom Fiori app that I developed for searching for Projects, WBS elements, and settlement cost centers. This blog will present details on how to read Project and WBS data using CDS views and table functions and then render the data in a tree table with a smart filter.

Here is a snapshot of the custom Fiori application showing Project, WBS element and settlement cost center data in a nice tree view table with a smart filter bar:

SAP S/4 HANA, SAP ABAP Exam Prep, SAP ABAP Certification, SAP ABAP Learning, SAP ABAP Preparation, SAP ABAP Career

So here is a sample project with nested WBS elements from SAP transaction code CJ20N.

Transaction code – CJ30N

In the SAP transaction, you can only show one project at a time, and you cannot search based on settlement cost centers. The customer needed to show all of the projects and WBS tied to settlement costs centers and display them in their hierarchical views. And that is why we built this custom Fiori App. Quite a few nice Fiori concepts are used in this app for rendering tree tables, downloading data to excel, manipulating the smart filters dynamically, changing the OData call to the backend, etc. My hope is that this blog will come in handy for you if are embarking on similar custom Fiori development projects.

So I had to built a custom app to show multiple projects with the child WBS elements and provide filters for projects, WBS, and settlement cost centers. Let’s dive in!

Here are the tiles for the custom Project WBS Fiori apps – one for the Hierarchy and one for the Analysis Report:

So here is the first Project WBS Hierarchy application main screen:

As we type in the Project, we have a nice value help fuzzy search implemented with the annotation and CDS view for the value help (code is below):

Project help fuzzy search

So if you select Project I-000066, here is the display of that Project and the child WBS elements rendered in a tree table rendering the hierarchy:

Project I-000066

You can also search for multiple projects by selected them in the Project value help:

Project value help screen

Here you can see multiple projects and the underlying WBS Elements. You can even select all of the Projects in the system and get the entire Projects and WBS Elements shown and later exported to excel (the code to download this data to Excel is also below):

Multiple projects

Here is the WBS Element value help:

WBS Element value help

Here is the value help for the settlement cost center:

Settlement Cost Center value help

So here is the CDS view ZRTR_PROJ_WBS_HIERARCHY called that is exposed as an OData interface that is consumed by the Fiori application: /sap/opu/odata/sap/ZRTR_PROJ_WBS_HIERARCHY_CDS/.

This view is using a table function ZRTR_WBSHIERARCHY_TABLEFUNC and associations to the standard SAP CDS views I_ProjectWithCodingMaskVH and I_WBSElementWithCodingMaskVH and custom CDS views ZRTR_I_SETTLEMENTCOSTCENTER_VH and ZRTR_WBS_STATUS

There are annotations for navigation and value help:

Here is the App.controller.js.

These methods may come in handy in your SAPUI5 coding for rendering the hierarchical data in the tree view, forward navigation to the subsequent app for costs, and the Project and WBS semantic objects, dynamic filter manipulation logic, and export data to excel functionality :

◉ _transformFlatToDeepData method – to transform data to tree structure with ParentCounter and Counter of the each Node – this is used to render the tree view

◉ onProjectPress and onWBSElementPress – for the CrossApplicationNavigation external navigation

◉ onDownloadTableButtonPress – to download to excel

◉ _getFilters – to get the filters from the UI and also change them on the fly – there is some nice tricks I have used here to get around the standard SAP functionality
