Requisition/PO Approval based on Accounting Flexfield Segment Parent Value

Hello,

customer requires to identify requisition and purchase order approvers based on the parent value of the one of the accounting flexfield segment. For example assume the accounting flexfield segment "Market". LOV for this segment contains the following values:

Value | Parent Value

10 | 01

20 | 01

30 | 02

40 | 02

Approver for parent value 01 is person A

Approver for parent value 02 is person B

It means that requisitions with values 10 and 20 in the Market segment should be approved by person A and requisitions with values 30 and 40 in the Market segment should be approved by person B.

Is there any BPM attribute keeping the parent values of the segment values? Does it help if we assign "Management Segment" label (qualifier) to the the Market segment?
