Approval procedure in Purchase req or PO- ECC 6.0

Question

Hai,
Can we set up a approval routing procedure in  Purchase requisition  or PO so that if a specific buyer converts / creates the PO -  and it's over a specific dollar amount - that it goes to another buyer for approval ?  Our department has a very high volume and we want to be able to allow a third party or user to create PO's on their own, but only below a threshold. 
Someone mentioned that if 1 ) buyer number and 2) dollar amount are both fields in the classification functionality, we can set-up the above procedure.
But, I do not know how this works. Can anyone suggest any solutions and briefly explain how to set this up?
We are running ECC 6.0.
Thank you in advance!

Hi Sonali,
I've listed down VERY BASIC steps below but hopefully it could guide you through configuration.
Below is an example for Purchase order approval:
Assumption:
a. 2 Buyers
-   B01 = Buyer 1
-   B02 = Buyer 2
b. Amount
-   <=100USD = No Check
-   >100USD = Other Buyer Check
1. /nCT04 Create 2 characteristics (Buyer and Amount)
2. /nCL02 Create Class for PO approval (Class type is 032) and assign Characteristics created in step 1.
3. Define Release Procedures for PO (IMG> Materials Management> Purchasing> Purchase Order> Release Procedure for Purchase Orders)
3.1 Release Group - create release group and assign class created in step 2.
3.2 Create release code B1 and B2 (assuming that either buyer can approve the other's work)
3.3 Release indicator = R for released, B for blocked
3.4 Create 2 Release strategies
3.4.1 RS1 = B02 checks B01
Release Code is B2 (for Buyer B02)
Classficiation (Buyer=B01; amount is >100USD)
3.4.2 RS2 = B01 checks B02
Release Code is B1 (for Buyer B01)
Classficiation (Buyer=B02; amount is >100USD)
Note: This is a very basic example and you need to play around with the other system settings.  Also, it is possible to determine values dynamically via user-exit if the requirement is more complex.
