Comment 3 for bug 1163766

To jsut hack it out, just open hr_timesheet_data.xml and comment out like this

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data noupdate="1">
      <!---
        <record id="analytic_journal" model="account.analytic.journal">
            <field name="code">TS</field>
            <field name="name">Timesheet Journal</field>
            <field name="type">general</field>
        </record>

        <record id="hr.employee" model="hr.employee">
            <field name="journal_id" ref="analytic_journal"/>
        </record>
      -->
    </data>
</openerp>

Then installation of module will be done smoothly.

Later, Goto
Accounting >> Analytic Accounting > Analytic Journals
Create a new Analytic Accounting Journal with Journal Name "Timesheet Journal" ,Journal Code "TS", and Type "General"

Later Goto "Human Resources" > "Employees"
Take each employee and goto "HR Settings" and put Analytic Journal to "Timesheet Journal" and make sure the product should be selected which you are timely billing like "Time based Software Development / Service"
