partial packing slip posting


I need what are the parameters required to post a partial posting packing slip set up details.

There are no separate setups for that.

Enter the Receive Now(partial receiving) quantity in Purchase Lines in Quantity tab. Now post the packing slip by setting the Quantity Parameter to “Receive Now”…

I did like that only,but getting error as shown below.

Cannot create a record in Dimension history for documents (InventReportDimHistory). Type: None, .
The record already exists.I need details regarding this erroe.
