• What is the cause and solution for SAP error message SADL_GW_DT_SB_UI030 - CDS-Entity '&1' must not contain parameters ?

  The SAP error message SADL_GW_DT_SB_UI030 indicates that a Core Data Services (CDS) entity is incorrectly defined with parameters. In the context of SAP, CDS views are used to define semantically rich data models, and they are often consumed by OData services. However, certain types of CDS entities, particularly those intended for use in OData services, should not contain parameters.
  Cause
  The error occurs when a CDS entity is defined with parameters, which is not allowed for entities that are intended to be exposed as OData services. Parameters in CDS views are typically used for filtering or other dynamic behavior, but when defining an entity for OData, the entity must be static and not require parameters.
  Solution
  To resolve this error, you need to modify the CDS entity definition to remove any parameters. Here are the steps you can follow:
  
  
  Open the CDS View Definition: Locate the CDS view that is causing the error in your ABAP development environment (e.g., Eclipse with ABAP Development Tools).
  
  
  Remove Parameters: Check the definition of the CDS view for any parameters. Parameters are typically defined in the @AbapCatalog.sqlViewName or @AbapCatalog.compiler.compareFilter annotations. Remove these parameters from the definition.
  
  
  Adjust the Logic: If the logic of your CDS view relies on parameters for filtering or other purposes, consider using other methods such as:
  
  Using Filter Expressions: Instead of parameters, you can use filter expressions in the OData service to achieve similar functionality.
  Creating Separate Views: If you need different variations of the data, consider creating separate CDS views for each variation instead of using parameters.
  
  
  
  Activate the CDS View: After making the necessary changes, activate the CDS view.
  
  
  Test the OData Service: Once the CDS view is activated, test the OData service to ensure that it works as expected without the parameters.
  
  
  Related Information
  
  CDS Views: Core Data Services (CDS) are a way to define data models in SAP that can be consumed by various applications, including Fiori apps and OData services.
  OData Services: OData is a standard protocol for building and consuming RESTful APIs. In SAP, OData services are often generated from CDS views.
  SAP Documentation: For more detailed information, refer to the official SAP documentation on CDS views and OData services, which provides guidelines on how to define and use them correctly.
  
  By following these steps, you should be able to resolve the SADL_GW_DT_SB_UI030 error and successfully define your CDS entity for use in OData services.
