how to create invoice with multiple payitems using bssv in jde

The requirement is to create multiple payitems with their corresponding GL lines using bssv

when i use the ARInvoiceManager BSSV, it allows  to create multiple payitems at the invoice level; however, the GL details for both the payitems are the same. they are not unique

(i.e) the GL detail section in the payload is non-repeating one; hence the payitems have the same data populated in them
