• What is the cause and solution for SAP error message DAAG_REST_HANDLER007 - Parameter &1 in view &2 can only use EQ Operator ?

  The SAP error message DAAG_REST_HANDLER007 indicates that a specific parameter in a view is restricted to using only the equality operator (EQ). This typically occurs when you are trying to use a different operator (like NE, GT, LT, etc.) for a parameter that is defined in the view to only accept equality checks.
  Cause:
  
  Parameter Definition: The parameter in the view is defined in such a way that it only allows equality checks. This is often the case for certain fields that are meant to be unique identifiers or keys.
  Query Construction: When constructing a query (for example, in an OData service), if you attempt to filter using an operator other than EQ for that parameter, the system will throw this error.
  
  Solution:
  
  Check the View Definition: Review the definition of the view in the SAP system. Look for the parameter that is causing the issue and confirm that it is indeed set to only allow the EQ operator.
  Modify the Query: If you are constructing a query (e.g., in an OData service or an API call), ensure that you are using the EQ operator for the parameter in question. For example, instead of using parameter NE value, you should use parameter EQ value.
  Consult Documentation: If you are unsure about the parameters and their allowed operators, refer to the documentation for the specific view or service you are working with. This can provide insights into how to properly construct your queries.
  
  Related Information:
  
  SAP OData Services: If you are working with OData services, familiarize yourself with the OData query options and how they relate to the underlying data model.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any known issues or additional guidance related to this error message.
  Debugging: If you have access to the backend, you can debug the service or view to see how parameters are being processed and where the error is being triggered.
  
  By ensuring that you are using the correct operator for the specified parameters, you should be able to resolve the error and successfully execute your query.
