Purchase order not getting Updated to APO

Hello All ,

What we are doing right now is

• (outbound) delivery is created automatically as soon as we create the STO (Purchase Order) via BAPI_PO_CREATE1

Now only the second schedule line is getting updated and the other are not getting updated in APO automatically unless we push them to APO. I have attached a snap shot of CCR and here you can see we do not have any 2nd schedule line . Why is that only one schedule line is getting updated but not others.

Regards,

Nick
