Delete filters from Fiori ABAP backend

I tried to delete line from it_filter_select_options but don't know how. Is there any method to do that?

My URI passes the value in filter but sometimes in some specific conditions I don't want to filter with it, but at the same time I want to filter with others values.

if foo = 'xyz'.

  delete it_filter_select_options where property = 'foo'.

  call method /iwbep/cl_mgw_data_util=>filtering
    exporting
      it_select_options = it_filter_select_options
    changing
      ct_data = et_entityset.
endif.

gives this syntax error at line delete it_filter_select_options where property = 'foo'.:

field can't be changed

  1. Please use io_tech_request_context->get_filter( )->get_filter_select_options( ).

  2. Uncheck the filter checkbox for the fields you don't want to be able to filter. (see Transaction SEGW, double-click your relevant OData entity)

  3. Don't evaluate the filters you don't want in the situations you mean programmatically.

IMPORTING defines input parameters. When the method is called, an appropriate actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which pass-by-reference is defined cannot be changed in the method.[1]

Save the filter select options in an local table.

Data(lt_select_options) = io_tech_request_context->get_filter( )->get_filter_select_options( ).

Now you can modify the lt_select_options.

if foo = 'xyz'
"delete lt_select_options[ property = 'foo' ]-select_options[ sign = 'I' ].
delete it_select_options where property = 'foo'.
call method /iwbep/cl_mgw_data_util=>filtering
  exporting
   it_select_options = lt_select_options
  changing
   ct_data = et_entityset.
endif.
