Multiple units asset depreciation issue

Hi,

We are using EBS Financial Modules since January of this year, so few months now and we have uploaded all historic data using API interfaces for each module, including Assets.

We are facing an issue when it comes to put in use one item of several items of an historic asset which is stored in warehouse and is not depreciated till it is assigned for use to an employee of the company.

Our common procedure for asset procurement is as follows:

1.ex. We purchase assets where the invoice has only one line with 3 units and respective price of 1000, so the total purchase is 3000.
