How To Fix ESH_ENG_CDSVAL_ES002 - Parameter &1: No fitting @Environment.systemField-annotation

SAP Error Message - Details

• Message type: E = Error

• Message class: ESH_ENG_CDSVAL_ES - ES-CDS/ABAP: Validation of domain @EnterpriseSearch

• Message number: 002

• Message text: Parameter &1: No fitting @Environment.systemField-annotation

What causes this issue?

It does not make sense to use view parameters in general with search
views; they are used in a generic application which cannot set them at
run time.
There are a few exceptions to this rule. For the application to be able
to recognize and to interpret those, the parameters in vies annotated by
@EnterpriseSearch.enabled have to be annotated by
@Environment.systemField; the possible values are: #APPLICATION_USER,
#SYSTEM_DATE, #SYSTEM_LANGUAGE.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If possible, annotate the parameter with @Environment.systemField, using
one of the above values.
Otherwise, remove the parameter from the view definition. If the
parameter is contained in a view used by the current search view, its
value has to be set statically in the definition of the current search
view.

• What is the cause and solution for SAP error message ESH_ENG_CDSVAL_ES002 - Parameter &1: No fitting @Environment.systemField-annotation ?

  The SAP error message ESH_ENG_CDSVAL_ES002 indicates that there is an issue with a parameter in a Core Data Services (CDS) view or a related query where the system is unable to find a fitting @Environment.systemField annotation for the specified parameter. This typically occurs in the context of SAP's Enterprise Search or when working with CDS views that are expected to interact with the environment in a specific way.
  Cause:
  
  
  Missing Annotation: The most common cause of this error is that the CDS view or the associated data model does not have the required @Environment.systemField annotation for the specified parameter. This annotation is necessary for the system to understand how to handle the parameter in the context of the environment.
  
  
  Incorrect Parameter Usage: The parameter might be incorrectly defined or used in the CDS view, leading to the system being unable to resolve it properly.
  
  
  Version Compatibility: There may be compatibility issues with the version of SAP you are using, especially if the CDS views or annotations have been updated in newer releases.
  
  
  Solution:
  
  
  Add the Missing Annotation: Check the definition of the CDS view or the relevant data model and ensure that the parameter in question has the appropriate @Environment.systemField annotation. The annotation should specify how the parameter interacts with the system environment.
  Example:
  @Environment.systemField: 'YourField'
  define view Your_CDS_View as select from Your_Table
  {
      key YourField,
      ...
  }
  
  
  Review Parameter Definitions: Ensure that all parameters used in the CDS view are correctly defined and that their types and usages are appropriate.
  
  
  Check Documentation: Refer to the SAP documentation for the specific version you are using to understand the requirements for annotations and parameters in CDS views.
  
  
  Update or Patch: If you suspect that the issue is related to a bug or compatibility problem, check for any available updates or patches for your SAP system that might address this issue.
  
  
  Consult SAP Notes: Look for relevant SAP Notes that might provide additional insights or solutions for this specific error message.
