Hi Nathan,
Posting ordinary depreciation entries manually (or could be through an upload program) and its reconciliation is a herculean task.
Needless to say, SAP is an awe-inspiring ERP. As we all know, its a robust ERP, which has many good functionalities. However, in my opinion, when we say a functionality cannot be adopted/changed when there is an activity in the company code, one has to agree that it is a limitation which is really not helping the customers.
Many thanks,
