Creating Custom Field Types. The widget that we help us to show our field for Reports not work

You can try setting the "custom_type" property as part of field_defs - to indicate what type of field it is. Whether it's a varchar/enum, etc. I don't think reports will recognize the non-default custom types by default. Eg:

$dictionary['Account']['fields']['highlight_field']['custom_type'] = 'varchar';

I had the same issue here, I tried the "custom_type" adding in the vardefs and I confirm it does solve the problem.

Thank you Neeraja P

Unfortunately, it doesn't work for me. Any idea if it has anything to do with sugarcrm version?
