• What is the cause and solution for SAP error message SADL_GW_DT_SB_UI038 - CDS-Entity '&1' has parameter without types ?

  The SAP error message SADL_GW_DT_SB_UI038 indicates that there is a problem with a Core Data Services (CDS) entity in your SAP system. Specifically, the error states that the CDS entity &1 has a parameter that is defined without a type. This can lead to issues when the system tries to process or utilize the CDS entity, especially in the context of OData services or UI applications.
  Cause
  The primary cause of this error is that one or more parameters in the CDS entity definition are missing their data types. In a CDS view, every parameter must have a defined type so that the system knows how to handle the data. If a parameter is defined without a type, it leads to ambiguity and results in this error message.
  Solution
  To resolve this error, you need to check the definition of the CDS entity and ensure that all parameters are correctly defined with their respective data types. Here are the steps to do this:
  
  
  Open the CDS View: Use the ABAP Development Tools (ADT) in Eclipse or the SAP GUI to access the CDS view that is causing the error.
  
  
  Check Parameter Definitions: Look for the parameters defined in the CDS view. Ensure that each parameter has a corresponding data type specified. The syntax for defining a parameter typically looks like this:
  define view <view_name>
  with parameters
    p_param1 : <data_type>,
    p_param2 : <data_type>
  as select from <table_name>
  ...
  
  
  Add Missing Types: If you find any parameters that do not have a type, add the appropriate data type to each parameter.
  
  
  Activate the CDS View: After making the necessary changes, activate the CDS view to ensure that the changes take effect.
  
  
  Test the Changes: After activation, test the CDS view to confirm that the error has been resolved and that the view behaves as expected.

  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional context or solutions related to this error message.
  
  By following these steps, you should be able to resolve the SADL_GW_DT_SB_UI038 error and ensure that your CDS entity is correctly defined and functional.
