Hi All,
So we have a current process as :-

1. PO is created in Ariba with 1 line item , and Account assignment as I(i.e Statistical Internal Order- to track budget). 
2. This is interfaced to SAP. 
3. Expectation is how can we create multiple asset and post GR/IR to these assets (Distribute amount on IO with total qty) in SAP/ if can be done in Ariba. 
Accounting entry at time of GR:-
Asset 1 Dr.
Asset 2 Dr.
GR/IR Cr.
