AP Mass Additions Create- multiple OUs and FA Books

Hi Guys,

Need your advise on the following,

Scenario-

Client has 4 OUs-Two books (corporate) per LE.

One Clearing account mapped/used across two FA books i.e.XX_OFA_BOOK (XX_OU) and YY_OFA_BOOK (YY_OU)

Same clearing account is used in Purchasing Categories.

User raised an invoice in AP against XX_OFA_BOOK and matched to a PO. but ran the Mass Additions Create program for YY_OFA_BOOK, this invoice get transferred to that YY_OFA_BOOK with BSV for a different OU i.e. invoice is raised for 1100 but when trasferred to FA, it goes to different book created for 1200.
