STO PO without delivery & PGI

Hi friends,

                   I am facing an issue in STO intercompany with billing scenario as mentioned below :

1.STO PO created in supplying plant ( S1) with doc type NB for 100 Qty

2.Delivery not created, PGI not done

3. GR done in receiving plant ( Since GR based IV tick in not maintained in PO)

4. Goods are also consumed in receiving plant

5. Now in supplying plant the PO is still displaying in MD04 for 100 Qty & the same needs to be billed for goods supplied.

Kindly let me know how to handle this scenario as this is an urgent issue.

Thanks.
