How to mass change posting date of parked logistics invoice verifications

I was wondering if someone can help...

We are looking if there is a standard SAP program available to mass change the posting date (to a new date in a new period) for a number of parked logistics invoice verification documents.

Example: Invoices are parked in e.g. April 2010; relevant information is not available before month end; so invoices will probably be posted somewhere in May or June or ...; users now have to individually change the posting date on each parked invoice to the new open month.

Is there any proces/program that could automate this task.

Thanks in advance for all your advice, feedback and comments.

Best Regards,

Luc Vernieuwe.
