• What is the cause and solution for SAP error message FDT_CP_MSG401 - Table/View annotation missing in data object "&1" ?

  The SAP error message FDT_CP_MSG401 indicates that there is a missing Table/View annotation in the data object specified by "&1". This error typically occurs in the context of SAP Fiori or SAP Gateway services when the system expects certain metadata annotations to be present for a data object, but they are not found.
  Cause:
  
  Missing Annotations: The data object (like a CDS view or a data model) does not have the required annotations defined in its metadata. Annotations are used to provide additional information about the data model, such as how it should be displayed in the UI or how it should behave in certain contexts.
  Incorrect Configuration: The configuration of the data model or the service might be incorrect, leading to the absence of expected annotations.
  Transport Issues: If the data object was transported from one system to another (e.g., from development to production), the annotations might not have been included in the transport request.
  
  Solution:
  
  
  Check Annotations: Review the data object (e.g., CDS view) to ensure that the necessary annotations are defined. You can do this by checking the source code of the CDS view or the relevant data model.
  
  Ensure that the @AbapCatalog.sqlViewName and @ObjectModel.usageType annotations are present, among others.
  
  
  
  Add Missing Annotations: If annotations are missing, you will need to add them to the data object. This may involve modifying the CDS view or the data model to include the required annotations.
  
  
  Activate the Object: After making changes, ensure that you activate the data object. In SAP, changes to CDS views or data models need to be activated for them to take effect.
  
  
  Check Transport Requests: If the issue arose after a transport, verify that the transport request included all necessary objects and annotations. If not, you may need to create a new transport request that includes the missing annotations.
  
  
  Debugging: If the issue persists, consider debugging the service or the application that is trying to access the data object. This can help identify where the missing annotations are causing issues.
  
  
  Related Information:
