Setting approval level for credit management in SD

Question

Dear Gurus,
I have a case like this:
My client would like to use credit management in SD. They have few approval levels for for credit limit release.
Exp: With SD has amount under from 1000$, Mr. A has the right to approve and release it
        With SD has amount bigger than 1000$, Mr. A  have to release it and then Mr. B check again afterwards Mr. B can reject and release it up to his decision.
As I see in SAP, maybe there is only one level for check and after release the SO doesn't need other approve anymore. But I am still concerning about how to find or config to satisfy this requirement.
Thank for nice support!

In our case we have maintained a view named as "ZVW_OAR_WF_CTRL" which is created by our ABAPer.
The fields in this view are
   FIELD NAME                              DATA ELEMENT         TYPE         LENGTH
1) MANDT                                          MANDT                         CLNT             3
2)PROCESS                                      ZDE_WF_PROCESS      CHAR           2

You can ask your ABAPer such that your view contains the above mentioned fields and in the the approvers you have to enter the "Pernr id" s of approver s which can be taken from HR people.
