Help with an initial filter SuiteCRM

I have a module called Legalizations, in which it has a field related to a module called accumulator, this relationship is Many to one. The drawback is that I want to apply an initial filter to only show me the accumulators that have been open at the time of creating a new legalization.

ACCUMULATOR MODULE

LEGALIZATION MODULE

When looking in the accumulator field of the legalizations module, the accumulator should not appear highlighted since it has a "closed" status, modify the following file: ./ custom / modules / cml_legalizaciones / metadata / editviewdefs. php

which was as follows:

1 => 
          array (
            'name' => 'cml_acumulador_cml_legalizaciones_name',
            'displayParams' =>
            array(
                'initial_filter' => array(
                '&estado_c_advanced = abierto',
                ),
            ),
          ),

but it still does not work for me.
