Remote assistance with PASI on the checking of NAV 2009 problem of GSRI. We investigate where the problem is coming from. They asked for the sample APV that has been missing or deleted. But still we can't see it if it is there or it has been posted already. We also checked on the Posted Purchases Invoices but the sample APV is not  there. We checked on the Server side and on the database but the same records cannot be found. Since this happened last week and there are too many changes on the NAV the vendor didn't advise to restore the data but instead just to retransact the data that were loss. The user agreed to this alerady.
