E1 upgrade from Xe > 9.0 > 9.1
in preparation to upgrade to 9.1 in 8 to 10 months, I need to know what the consequences would be for an upgrade with these challenges:
- There are a set of Procurement activities that were modified during the Xe days including approvals and tolerances, then the same mods were "transfered' to 9.0 and further enhanced with more mods when some activities did not behave as some business units expected.
- There are a set of Maintenance (CAM) PM and WO activities that were also modified during the Xe days including statues and workflows, and parts attachments were "transfered' to 9.0 and further enhanced with more mods when some activities did not behave as some business units expected. I don't know what they did to the FInancial suite. Also there were mods made to the Inventory, Fixed Assets, Work Order Management.
