Hello Isa MArzooq,

To render project associated with customer, we need to update few things 

At view level set below code

Also you need to set computer method

project_name = fields.Many2many(
        'project.project', string="Project Names", compute='_compute_project_name')

    @api.depends('partner_id')
    def _compute_project_name(self):
        for move in self:
            if move.partner_id:
                # Fetch all projects related to the partner_id
                projects = self.env['project.project'].search(
                    [('partner_id', '=', move.partner_id.id)])
                move.project_name = projects
            else:
                move.project_name = False

I hope this will help you. Please let me know if you need any further support.

Thanks

Hello,

I believe that you have created a new field "project_id" which is many2one of project.project model.

Now the project.project model has many2one field called "partner_id" of res.partner model.

As per your requirement, we need to allow the user to choose a project which has the same  partner as selected in invoice.

Add following domain in form view to define project_id field:

Thanks & Regards,
