Hi ,
There are lot of standard report like COOIS /COHV/CO46 where you can see un confirmed order
In case COOIS , you have to select the Order System status CNF , PCNF and mark exclude check box and also enter the Order type and Plant code .Here you can also exclude DLV , PDLV , CLSD , TECO etc .Or you may have to need the order which are CRTD , REL , PCNF only .
It will list down all those order .
Other wise , you can go to SQVI and build a query along with AUFK , AFVC , AUFM , AFRU
Regards
