<!-- Add New Button -->

</xpath>

</field>

</record>

</odoo>

But it is not appearing in order.. What is want

1) Draft

2) After Confirm

3) Substitute Approval

4) Then rest as standard

Hi,

Instead of using selection_add try using selection and replace all the states

Hii,

How to know that only the substitute employee should approve this leave?

Means the new Substitute Approval button in the header should be visible to Substitute Employee only.

Thanks,

Hii,

One more question along with the above one.

Now the workflow state is validate_substitute (the new state I added) and when I click the Approve button, its giving me following odoo error "Leave request must be confirmed ("To Approve") in order to approve it."

While state validate_substitute comes after confirm.

What could be the reason?

Thanks,

Hii @Niyas Raphy and @Mihran Thalhath

How to handel above two questions.

Thanks,
