Portugal legal requirement on Invoice in the box

Hello All,

I believe there is a 2012 legal requirement in Portugal to insert Invoice in the Box.

To explain in detail companies in Portugal are supposed to insert sales Invoice along with the materials when they are dispatched from the plant. THis effecdtive means that Invoice needs to be created before PGI.

Now in SAP Standard it is possible to create Invoice before but my client does not allows it.

Has anybody here heard of this requirement in Portugal? If yes then how are you handling it?

Thanks,
