No quantity could be derived from item 00001 in T_OIGISVMQ

Hi,

I get following error while actualizing the ticket:

No quantity could be derived from item 00001 in T_OIGISVMQ.

Message class : O9, Message no. : 868.

I saw a thread : http://forums.sdn.sap.com/thread.jspa?threadID=1440255

But this did not help much.

I crreated a backend PO and created a nomination for this PO. Later created a ticket for this nomination.

But then this error happens after the shipping notification is created.

The strange thing is: This error has started showing up all of a sudden! I have already created several tickets folowing the same procedure but hen this error did not occur!

Has anyone faced this problem before?

Thanks & Regards,

Kamini
