Sales Order number is not showing in MD04

Hi Gurus  ,

I have got one case where  Sales order number is not showing  in MD04 screen  . This sales order , line item  has already delivered , PGI &  billing document also been generated  . Moreover accounting document is also been created .As cheeked & found that it is not shwoing in MD04 screen  because at  the time sales order creation  availability check “01” was maintained  which has sum up all the  requirement in one  particular day ( Also as

per SAP note -70408) .

Now because  all the subsequent document has been generated  for sales order so we can not mark it for “Rejection for rejection “  & to create new  sales order  with  availability check “02” in material master .

Please let  me know the possible solution for the same or  if any  sap note would  be required to get the sales order number in MD04  .

Thanks  ,

Aman
