• What is the cause and solution for SAP error message /UI5/MP_CP_OVP000 - If "dataSource" is provided, "model" must be provided, too ?

  The SAP error message /UI5/MP_CP_OVP000 indicates that there is a configuration issue in your SAPUI5 application, specifically related to the definition of a data source and its associated model. The error message states that if a "dataSource" is provided, a "model" must also be provided.
  Cause:
  This error typically occurs when you are trying to define a data source in your SAPUI5 application without specifying the corresponding model. In SAPUI5, a data source is used to connect to a backend service, and a model is required to bind the data from that service to the UI components. If the model is not defined, the framework does not know how to interpret the data coming from the data source.
  Solution:
  To resolve this error, you need to ensure that both the data source and the model are properly defined in your application. Here are the steps to do that:
  
  
  Define the Data Source: Make sure you have defined the data source in your manifest.json or in the appropriate configuration file. This typically includes the service URL and any necessary parameters.
  Example:
  "dataSources": {
      "myDataSource": {
          "uri": "/path/to/service",
          "type": "OData",
          "settings": {
              "odataVersion": "2.0"
          }
      }
  }
  
  
  Define the Model: After defining the data source, you need to create a model that uses this data source. This can also be done in the manifest.json file.
  Example:
  "models": {
      "myModel": {
          "dataSource": "myDataSource",
          "settings": {
              "defaultBindingMode": "TwoWay"
          }
      }
  }
  
  
  Check Binding: Ensure that your UI components are correctly bound to the model. For example, if you are using a table or list, make sure that the items are bound to the correct path in the model.
  
  
  Test the Configuration: After making the changes, test your application to ensure that the error is resolved and that data is being fetched and displayed correctly.

  Version Compatibility: Ensure that you are using compatible versions of SAPUI5 libraries, as certain features may vary between versions.
  
  By following these steps, you should be able to resolve the error and ensure that your SAPUI5 application functions correctly.
