CDS - Dynamic Semantic Navigation

👋 Hello Everyone!

Dynamic Semantic Navigation in CDS

I recently encountered a scenario where I needed to navigate to different apps based on the type of a technical object — Functional Location or Equipment.

Since CDS doesn’t support dynamic semantic object/action assignment, I implemented a workaround by grouping two fields into a single column, each configured with its own semantic object and action. Based on the object type, I conditionally hide one of the fields.

For example, if the object type is Equipment, the column shows a link that navigates to the Equipment app. If it’s Functional Location, it displays a link to the Functional Location app.

Below is the CDS logic that enables this dynamic navigation: 

@AccessControl.authorizationCheck: #NOT_REQUIRED
define view entity ZR_TechnicalObject
  as select from I_TechnicalObject
{
  key TechnicalObject,
  key TechObjIsEquiporFuncnlloc,

  @UI.lineItem: [{ position: 10, 
  				   label: 'Technical Object', 
                   qualifier: 'Structure', 
                   type: #AS_FIELDGROUP, 
                   valueQualifier: 'TechnicalObject' }]
  @ObjectModel.text.element: ['TechnicalObjectDescription']
  @UI.fieldGroup: [{ qualifier: 'TechnicalObject', 
  					 semanticObject: 'MaintenanceObject', 
                     semanticObjectAction: 'displayEquipment', 
                     type: #WITH_INTENT_BASED_NAVIGATION, 
                     hidden: #(HideEQUI) }]
  Equipment,

  @ObjectModel.text.element: ['TechnicalObjectDescription']
  @UI.fieldGroup: [{ qualifier: 'TechnicalObject', 
  					 semanticObject: 'MaintenanceObject', 
                     semanticObjectAction: 'displayFunctionalLoc', 
                     type: #WITH_INTENT_BASED_NAVIGATION, 
                     hidden: #(HideFL) }]
  FunctionalLocation,

  @UI.lineItem: [{ position: 20, qualifier: 'Structure' }]
  TechnicalObjectDescription,

  case when TechObjIsEquiporFuncnlloc = 'EAMS_EQUI' 
  	   then cast('' as abap_boolean) 
       else cast('X' as abap_boolean) end as HideFL,
       
  case when TechObjIsEquiporFuncnlloc = 'EAMS_FL' 
       then cast('X' as abap_boolean) 
       else cast('' as abap_boolean) end as HideEQUI
}

This workaround allows dynamic navigation while keeping your UI clean and flexible.

RAP - Real Time UI Updates Using Event-Driven Side Effects

Hello Everyone! 👋 Real-Time UI Updates in RAP Using Event-Driven Side Effects We've all come across situations where something changes in the backend, and we want those updates to automatically reflect in the UI without manually refreshing the page. In traditional setups, we used ABAP Channels for this but how can we achieve the same in RAP? Here's a simple example: I'm updating the travel status in one class/report, while the app is open in parallel. As soon as the status is updated in the backend, it automatically reflects in the UI no refresh needed! This is made possible through Event-Driven Side Effects . This is useful when: Background jobs update data We want to notify users with messages in real time Multiple users are working on the same data simultaneously Step 1 – Add the event-driven side effects in the BDEF managed with additional save .... .. define behavior for YR_YABS_TRAVEL...

ABAP - Create CSV Files Easily Using CL_CSV_FACTORY

-
Hello Everyone! 👋 Create CSV Files Easily in ABAP Using CL_CSV_FACTORY In many scenarios, we need to download internal table data in CSV format. Often, the requirements vary for example, using different field separators such as semicolon (;), comma (,). Additionally, we may need to include a header row and format fields like date, time, or timestamp. All of this can be handled very easily using the CL_CSV_FACTORY class. The best part is that this class is also available in the SAP Public Cloud. Step 1 – Select the Data SELECT FROM vbak FIELDS vbeln, vbtyp, erdat INTO TABLE @DATA(lt_test) UP TO 10 ROWS. Step 2 – Create a Simple CSV with Header This example generates a CSV using a semicolon as the delimiter and includes the header row automatically. DATA(lv_xstring_v1) = cl_csv_factory=>new_writer( )->set_delimiter( ';' )->set_write_header( abap_tr...
