Unable to transfer AP invoice matched to a PO to fixed assets through Mass Additions

Summary:

PO matched invoices are not being interfaced to FA module

Content (please ensure you mask any confidential information):

Steps:

1. Created a PO matched invoice
2. set flag "Track as asset" on the invoice line
3. Validated and approved the invoice
4. Accounted the invoice in final mode (Account type: Expense)
5. Run Mass additions (same date as the invoice accounting date)
6. Nothing created in fixed assets

Is there anything else I am missing? And what is the best practice to transfer PO matched invoices (3 way match) to Fixed assets with Capitalized asset type? Currently this kind of invoiced generate an expense type account in accounting entried, do we have to override it with an asset type account ?
