Retrieve the Deleted ABAP Code?

Dear All,

Scenario:

Under the one transport request there are 2 tasks created for 2 different user-ids.

Under the first task first Abaper start with the ABAP CLASS and Methods development and once its finish he released the task.

Its is still present in the development system with the task release state. ( Transport request is not released )

After some time second Abaper start with the same development again with the same classes and methods.

But by mistake he deleted the code present inside one method and now as every thing present in the development system he is not able to retrieve the old code from version management.

Is there any possibility to retrieve the old deleted code of method?

Thanks in advance
