We have recently implemented Oracle (including Oracle Project Costing). We are a mall operator (among other things) and are using the Project Costing module to track our marketing expenditure. Each mall has been set-up as a seperate operating unit. We now have a challenge that the business wants to raise a PO across multiple malls but the system will not allow this because, apparently, you cannot raise PO lines for projects that are not in the operating unit specified in the header. In fairness to the solution implementer this was explained to the business who said at the time that was accepted (now they are jumping up and down). Has anyone out there a solution to this particular issue or have had a similar experience. Any help is much appreciated.
