  The SAP error message ESH_ENG_CDSVAL_ES018 typically indicates an issue related to the use of a character format in a CDS (Core Data Services) view or a related data model. This error suggests that a specific field or value is expected to be in a character format, but the provided input does not meet that requirement.
  Cause:
  
  Data Type Mismatch: The error usually arises when a field that is expected to be of a character type (like CHAR, STRING, etc.) is being populated or processed with a different data type (like numeric or date).
  Incorrect Field Usage: The field in question may be used in a context where a character format is required, but the input does not conform to that requirement.
  Configuration Issues: There may be issues in the configuration of the CDS view or the underlying data model that lead to this error.
  
  Solution:
  
  Check Data Types: Review the data types of the fields being used in the CDS view. Ensure that any values being passed to fields expected to be in character format are indeed character strings.
  Modify Input Values: If you are passing values to the CDS view, ensure that they are formatted correctly as character strings. For example, if you are passing a numeric value, convert it to a string format.
  Review CDS View Definition: Check the definition of the CDS view to ensure that the fields are correctly defined and that the expected data types align with the actual data being processed.
  Use Technical Description: If the error message suggests using 'technicalDescription', ensure that you are using the correct field or method to retrieve or display the technical description in the expected format.
  Debugging: If the issue persists, consider debugging the CDS view or the associated ABAP code to trace where the data type mismatch is occurring.
