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

ESH_ENG_CDSVAL_ES002 - Overview

• 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.
