How OE LInes / WSH Delivery Lines are Transferred to / Populated in RA Interface.

Hi,

Product version and release is R12.1.3.

It is  observed that sometines, One Sales Order is splitted into more than one RA Invoice. After reading the Setion-2  titled as 'Multiple Invoice Transactions Created When Expecting One), and it's sub-section b titled as  (Consider the frequency in which AutoInvoice is executed) of  the under-given  document, it seems that transferring of OE Lines to RA Interface may have some problems. 

As I understand that 'AutoInvoice Master Program', while executing for transfer of OM data to AR, cannot know the OE Lines present in the RA Interface are all-lines of an SO or part-of-of-that.
