@Nagah.khaled , It’s not possible to control the permission of a particular activity in company-wise or site-wise in IFS, if the users have access to those companies/sites. So, if the user has access to all 4 companies, it’s not possible to enable add(New) button in Manual Supplier Invoice window for only one company.

However, you would use a custom event for this requirement, with an event action of Online SQL Statement, to generate an error message upon saving. So, ideally it would not disable the Add (+) button, and instead it will not allow to save the record.

Thanks,

Hi @Nagah.khaled ,

You can remove access to the voucher type for the company. 

In the window ‘User groups for voucher series’  you can remove all the user groups for the needed companies.

New button will be available but no invoice can be created till the end.
