Have to post multiple invoices using BAPI_ACC_DOCUMENT_POST

HI ,

I have to post multiple invoices using BAPI.

How the data coming into internal tables is,

Now i have to post 4 invoices here, when ever the reference field changes, then it needs to be post 1 INVOICE. My Internal table contains all these Data, Only i need the best logic to post these 4 invoices at time.

Thanks in advance.
