SAP System allowed to do service confirmation for more than PO Service Quantity (2 AU).
Please check the Service quantity ( 2 AU) and PO History ( 101 two documents for 2 quantity)
I have done service confirmation for 2 AU and deleted service entry sheet but system not generated 102 document.
After that I have done one more service confirmation for 2AU.
But while doing Invoice system is giving 2 line items with 2 quantities to do invoice.
System allowing to do invoice for double quantity and double amount.
