MOAC FOR I PROCURMENT

Dear Freinds

I have one requirement of my client where they want to use the MOAC functionality for i procurement. At the moment when i login into i procurement using specific responsibility then application allows me to work only for a single OU i.e. for which responsibility is assigned. Is there any specific set-up through which I can use the MOAC function on i procurement web pages . For example loggin through a single responsibility and I should be able to create requisition for multiple OU's.

Thanks
