A/P Invoice, Asset number only once

Hi,

we have a customer running Business One 9.0 in production. This customer is now doing tests with the FA module, and they found what looks to be a limitation in the way the want to use it.

On some A/P Invoices, the same asset number appears on more than one line. But when trying to add the invoice, a message states that an Asset number can appear only on one line.

I have two questions: why isn't it allowed to have the same Asset number on more than one lines, and is it possible to achieve in a different way ?

I asked the customer, and was told that the Purchase Order are created in this way and when the PO is copied to the invoice, they can't create it. I don't know why they buy these assets in this way.

Thanks
