• What is the cause and solution for SAP error message EIT_GW_UI_TEXT007 - Value of navigation property &1 must be an array. ?

  The SAP error message EIT_GW_UI_TEXT007 indicates that there is an issue with the value of a navigation property in an OData service. Specifically, it states that the value of the navigation property must be an array, but the provided value is not in the expected format.
  Cause:
  This error typically occurs in the following scenarios:
  
  Incorrect Data Structure: The navigation property is expected to return multiple values (an array), but the data being sent is a single object or a different data type.
  OData Service Configuration: The OData service may not be correctly configured to handle the navigation property as an array.
  Client-Side Code: If you are using a client-side application (like SAP Fiori or any other UI5 application), the code may be incorrectly handling the data, leading to a mismatch in expected data types.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the OData Model: Ensure that the OData model is correctly defined. The navigation property should be defined as a collection in the metadata (EDMX file or service definition).
  
  
  Inspect the Data Being Sent: Verify the data being sent to the OData service. If you are sending a single object, you need to wrap it in an array. For example:
  {
      "navigationProperty": [
          {
              "property1": "value1",
              "property2": "value2"
          }
      ]
  }
  
  
  Update Client-Side Code: If you are using a UI5 application, check the code where the data is being prepared for submission. Ensure that you are correctly handling the navigation property as an array.
  
  
  Debugging: Use debugging tools to inspect the request payload being sent to the OData service. This can help identify if the navigation property is being sent as an array or not.
  
  
  Consult Documentation: Review the SAP documentation for the specific OData service you are using to ensure that you are following the expected data structure.
  
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it handles navigation properties can provide insights into how to structure your data correctly.
  SAP Gateway: Familiarize yourself with SAP Gateway and how it manages OData services, including the configuration of entity types and navigation properties.
  SAP Community: Engage with the SAP Community forums for additional support and to see if others have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
