Auto receipt for inbound delivery after X days

Hi Gurus,

I am currently implementing SAP at a customer who is ordering finished goods from China.

Inbound delivery is created automatically and sent via EDI to SAP when the supplier issues the goods from China.

After 10 days, when the goods are in international waters, goods receipt should be posted to goods in transit.

Is it possible to have the GR posted automatically?

I know we can have the auto GR immediately when creating inbound delivery (with control key) but can we somehow manage this delay?

Inbound delivery created 10.06.2016, so GR automatically posted 20.06.2016.

Thank you!

Regards,

Megan
