Dear Drees Far,

Good question,

As per your requirement create one new separate selection field which have two value related to report name and also you can apply radio widget in selection field for choices.

Also you need to create two button for reports.

Now using attrs you can do visible or invisible button as per selection field value.

Hope this suggestion help for you.

Updated code:

Step-1: Need to create one new selection field in py file

report_list = [('report1', 'Report1'), ('report2', 'Report2')]

columns = {

     'report_choice': fields.selection(report_list, 'Reports Choices')

} 

Step-2: Define selection field in xml file.

<field name="report_choice" widget="radio"/>

<button name="your method-1" type="object" string="Report1" attrs="{'invisible':['|',('report','=', False), ('report', '=', 'report2')]}"/>

<button name="your method-2" type="object" string="Report2" attrs="{'invisible':['|',('report','=', False), ('report', '=', 'report1')]}"/>

Hope this code help for you

Best Regards,
