PN:Property Manager AR Invoice Series

       Hi,

   How does Oracle Property Manager select the Transaction Batch Source to automatically assign the Transaction Number when importing to Receivables?
  I have this scenario where depending on the Property which is setup by branch, the Transaction Number will also be by branch.

   For example. i have 100 Properties setup in Oracle Property Manager.
   I will also have 100 Transaction Sources setup , (N>Setup>Transactions>Sources), each having automatic transaction numbering by series.
   How do i assign this series number when i generate the lease in Property Manager by branch?

   Thanks a lot for all the help!
