I need help for the next issue (We use the version 6.1 ):

I have developed a new type of invoice according with our needs, the invoice is visible on Accounting -> Customers/Suppliers -> Customer Invoices/ Supplier Invoices, click on an invoice, the section Reports (right side of screen- reports without wizard) The link of invoice is memored in the table "ir_values", and the report is memored in the table "ir_act_report_xml". The report is not memored on the database, so I don't have any object , I can not use the Access Rules for some rights. I need to hide the report (or the link of report) for some company. I tried to use the attribute invisible, for eg. attrs="{'invisible':[('company_id','=','2')]}", but is not working (for buttons is working).

How should I modify the next code to hide the report for a company with name "RO" or any other name?

<record id="p5_internal_invoice_md_id" model="ir.actions.report.xml">
