• What is the cause and solution for SAP error message /UI5/MP_CP_APP001 - Only a single dataSource with type 'OData' is permitted ?

  The SAP error message /UI5/MP_CP_APP001 Only a single dataSource with type 'OData' is permitted typically occurs in the context of SAP Fiori applications or SAPUI5 applications when there is an issue with the configuration of the application's data sources. This error indicates that the application is trying to define multiple OData data sources, which is not allowed in certain contexts.
  Cause:
  
  
  Multiple OData Data Sources: The primary cause of this error is that the application is configured with more than one OData data source in the manifest file or in the application configuration. SAPUI5 applications are designed to work with a single OData service for the main data binding.
  
  
  Incorrect Manifest Configuration: The manifest.json file may have multiple entries under the sap.app.dataSources section, where only one OData data source is expected.
  
  
  Version Compatibility: In some cases, the version of SAPUI5 being used may have specific restrictions or bugs related to data source configurations.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the manifest.json File:
  
  Open the manifest.json file of your SAPUI5 application.
  Look for the sap.app.dataSources section.
  Ensure that there is only one entry with the type OData. If there are multiple entries, you need to consolidate them into a single OData data source.
  
  Example of a correct configuration:
  "sap.app": {
      "dataSources": {
          "myODataService": {
              "uri": "/path/to/odata/service",
              "type": "OData",
              "settings": {
                  // additional settings
              }
          }
      }
  }
  
  
  Remove or Merge Data Sources: If you find multiple OData data sources, decide which one you need and remove the others. If you need to combine data from multiple services, consider using a single OData service that aggregates the required data or use a different approach to handle multiple data sources.
  
  
  Check for Dependencies: If your application relies on third-party libraries or components, ensure that they are not introducing additional OData data sources inadvertently.
  
  
  Test the Application: After making the necessary changes, test the application to ensure that the error is resolved and that the application functions as expected.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAPUI5 documentation for guidelines on configuring data sources in the manifest.json file.
  SAP Community: Check the SAP Community forums for discussions related to this error, as other developers may have encountered and resolved similar issues.
  Version Updates: Keep your SAPUI5 libraries updated, as newer versions may have improved handling of data sources and related configurations.
  
  By following these steps, you should be able to resolve the /UI5/MP_CP_APP001 error and ensure that your SAPUI5 application is correctly configured to use a single OData data source.
