delivery issue

Hi,

I created one material with sales & Accounting view only.

I upload material directly to Unrestricted stock with Movement type 561 in MB1C

Now i created one sales order i mentioned that storage location also

at the time of delivery I am getting the error that

" Sales order stock doesn't not exit"

this should not happen bcoz i am doing delivery directly from unrestr. then why system asking for sales order stock?

Regards,

Rahul
