Smart SAP Assistant

• What is the cause and solution for SAP error message /UI5/UI5_REP_LOAD021 - UIAD &1 was deleted as no inbound is defined in manifest.json ?

  The SAP error message /UI5/UI5_REP_LOAD021 indicates that a UI5 application is trying to load a component or resource that has been deleted or is not properly defined in the manifest.json file. Specifically, the message states that a UI5 application descriptor (UIAD) was deleted because there is no inbound defined for it in the manifest.json.
  Cause:
  
  Missing Inbound Definition: The manifest.json file for the UI5 application does not have an inbound definition for the specified UIAD. Inbound definitions are necessary for routing and navigation within the application.
  Incorrect Configuration: The application might have been misconfigured, leading to the absence of necessary entries in the manifest.json.
  Deleted or Renamed Components: If components or views have been deleted or renamed without updating the manifest.json, it can lead to this error.
  Versioning Issues: If the application was updated or migrated, there might be discrepancies in the manifest.json file.
  
  Solution:
  
  
  Check manifest.json: Open the manifest.json file of your UI5 application and ensure that there is an inbound definition for the UIAD that is being referenced. The inbound section should look something like this:
  "sap.ui.generic.app": {
      "routing": {
          "config": {
              "routerClass": "sap.m.routing.Router"
          },
          "routes": [
              {
                  "pattern": "",
                  "name": "YourRouteName",
                  "target": "YourTarget"
              }
          ],
          "targets": {
              "YourTarget": {
                  "viewName": "YourViewName",
                  "viewLevel": 1
              }
          }
      }
  }
  
  
  Add Missing Inbound: If the inbound definition is missing, you need to add it according to your application's routing requirements. Ensure that the pattern, name, and target are correctly defined.
  
  
  Review Application Structure: Ensure that all components, views, and controllers referenced in the manifest.json are present in the application structure. If any have been deleted or renamed, update the manifest.json accordingly.
  
  
  Check for Typos: Look for any typographical errors in the manifest.json that might prevent the application from recognizing the inbound definitions.
  
  
  Test the Application: After making changes, test the application to ensure that the error is resolved and that the application behaves as expected.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP UI5 documentation for detailed information on configuring the manifest.json file and understanding the routing mechanism.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to similar issues faced by other developers.
  Debugging Tools: Use browser developer tools to inspect network requests and console logs for additional context on the error.
  
  By following these steps, you should be able to resolve the error message /UI5/UI5_REP_LOAD021 and ensure that your UI5 application is correctly configured.
