Hi,

In test class you need to create look up records for Region and Company then you provide those ID's while creation of new expense report

You are attempting to put text into a lookup field.  A lookup field requires an id.  To get an id, you need to create an instance of Region and Company and insert those records.  Before you create a new expense report you need to do something like this (I don't know your object/fields so I'm just showing a simple example):

  Region__c region = new Region(Name = 'Russia');
  insert region;

Company__c company = new Company (Name = 'Genpact');
insert company;

Expense_Report__c PERObj = new Expense_Report__c(Name='Travel',Region__c=region.Id,Company__c=company.Id);
