Updating an Item using /RPM/ITEM_MODIFY

Hi Experts,

I am using /rpm/item_display and /rpm/item_modify FM to update an item. The code works fine if the user who is executing the applications has ACL permissions on the item. It gives authorization error if the user does not have ACL permissions.

The problem is we have a workflow scenario where a user submitts a change for approval and on approval we need to update the item. The Approver wont necessarily have ACL permissions on the item. I was trying to use FM /RPM/ACL_DISPLAY and /RPM/ACL_MODIFY to update the ACL during runtime, but it dint work.

Can we somehow update the item using a user which does not have ACL permission to item ? Is there any other way to achieve this ?

Thanks,

Yomesh
