Internal change after Release

Hi

Scenario

We are using internal order (Investment) for capital budgeting.

We have created two roles a)Z_FI_IOCREATION for order creation, change

and display and b)Z_FI_IORELEASE exclusively for releasing the order.

End users create the order and their HOD's release the oders.

Requirement

End users can change the order n number of times but only before

Release of the order.

After release of Order if the order is changed by end user the orders

should be available for Release again. This way we contol the change of

orders after approval. How this can be addressed.

Regards

Ganesh
