R12 SLA Separate Receivable Account by Different Revenue "Cost Center" segment value ??

  Dear Expert ,

          Does anyone have experience using SLA to separate receivable account by different revenue "Cost Center" segment value ?

          for example : one transaction , including two sales item , and set autoaccounting for Revenue "Cost Center" segment value from Standard Line

          and set autoaccounting for Receivable "Cost Center" segment value from Transaction Type ( it 's not allowed to set come from standard line )

          Then I set the account derivation rule for Receivable Account in SLA . add "Cost Center" segment and assign cost center value from "Transaction Item Sales Account" .. But it's not work ..

          Appreciate any  feedback  in advance.

  rg,
