• What is the cause and solution for SAP error message /UI5/MP_CP_UI5002 - Model requires either attribute 'dataSource' or 'type', not both ?

  The SAP error message /UI5/MP_CP_UI5002 Model requires either attribute 'dataSource' or 'type', not both typically occurs in the context of SAPUI5 applications when defining a model in the manifest or in the controller. This error indicates that there is a conflict in the model configuration where both the dataSource and type attributes are specified, which is not allowed.
  Cause:
  The error arises when you try to define a model with both dataSource and type attributes at the same time. In SAPUI5, a model can be defined using either a dataSource (which points to a specific data source defined in the manifest) or a type (which specifies the type of model, such as JSON, XML, etc.), but not both.
  Solution:
  To resolve this error, you need to modify the model definition in your application to use either dataSource or type, but not both. Here’s how you can do that:
  
  
  Check the Model Definition: Locate the model definition in your manifest.json file or wherever you are defining the model in your code.
  
  
  Choose One Attribute:
  
  If you want to use a dataSource, ensure that you remove the type attribute.
  If you want to use a type, ensure that you remove the dataSource attribute.
  
  
  
  Example:
  Here’s an example of how to define a model correctly:
  Using dataSource:
  "models": {
      "myModel": {
          "dataSource": "myDataSource",
          "settings": {}
      }
  }
  Using type:
  "models": {
      "myModel": {
          "type": "JSON",
          "settings": {
              "data": {
                  "key": "value"
              }
          }
      }
  }
  Related Information:
  
  Manifest.json: This is the configuration file for SAPUI5 applications where you define models, data sources, and other application settings.
  Data Sources: Data sources are defined in the dataSources section of the manifest.json and can point to OData services, JSON files, etc.
  Model Types: Common model types in SAPUI5 include JSONModel, XMLModel, ODataModel, etc. Each type has its own way of handling data.
  
  Debugging Tips:
  
  If you are unsure where the model is defined, search for the term myModel (or whatever name you are using) in your project files.
  Use the browser's developer tools to check for any additional errors or warnings in the console that might provide more context.
  
  By ensuring that you only use one of the attributes (dataSource or type), you should be able to resolve the error and successfully run your SAPUI5 application.
