Since the introduction of the IIA version 7 in April 2024, you have the possibility to modify an IIA which was previously mutually approved. In order to modify an IIA which is in Approved by all status, you have to find the IIA in the IIA>IIA List menu on the enhanced EWP Dashboard and click on it to open the Single View of it. When you open the Single View of the IIA, find the orange button Modify IIA which is located at the bottom right and click it.
You are able now to proceed to the modifications you like, same as when you Edit IIAs and then submit the IIA. Please note that you must edit at least one cooperation condition for the IIA to be considered as modified and sent to the partner, i.e. changing the contact details only is not considered as a modification.
After you submit the modified IIA, your partner will be notified about your changes and you are transferred to the Single View. The new status of the IIA is Submitted by You and you can see the Revert IIA button to be active now.
The last approval remains valid and you can revert it back to its previously state at any time until both of you and the partner HEI re-approve the IIA. This can be done with the Revert IIA button which allows you to revert the IIA to the previous version of it where it was in Approved by all status and therefore undo the modifications, in case you changed your mind. You may then start again with a new modification, as many times as you like. Learn more on how the Revert IIA button works here (link).
Note that you can only modify an IIA when it is either in Approved by all or Termination Approved by All statuses.
