Hi
1st part is explained by Rajneesh already
2nd part - When you settle IO, the IO is credited using Cost elements (Primary or Secondary)... You will always find the Order No there in these line items..
The debit posting may go to AUC recon account, which wont attract any IO postings unless you maintain the same IO in Asset master and the settings in T code ACSET
