  The SAP error message ESH_ENG_CDS_ABAP054 indicates that there is an issue with a Core Data Services (CDS) view in the context of the SAP Enterprise Search (SAP ESH) framework. Specifically, the error message states that a parameter (denoted as &1) does not have a fitting @Environment.systemField annotation.
  Cause:
  The error typically arises when:
  
  A CDS view is being used in a context where it is expected to have certain annotations that define system fields.
  The required @Environment.systemField annotation is missing for one or more fields in the CDS view.
  The CDS view is not properly configured to be used in the context of SAP ESH, which relies on these annotations to understand how to handle the data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view that is causing the error.
  Ensure that all relevant fields that are expected to be system fields have the @Environment.systemField annotation defined.
  
  
  
  Add the Missing Annotation:
  
  If you identify fields that are missing the @Environment.systemField annotation, add it to the field definitions in the CDS view. For example:
  @Environment.systemField: true
  field_name : data_type;
  
  
  
  
  Activate the CDS View:
  
  After making changes to the CDS view, make sure to activate it. This will ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  If the CDS view is dependent on other views or tables, ensure that those dependencies are also correctly annotated and activated.
  
  
  
  Test the Changes:
  
  After making the necessary changes and activating the CDS view, test the functionality that was previously causing the error to ensure that it is resolved.
