AME Rules based on Inventory Organization for Requisitions

Hi,

We have an requirement to use AME approvals based on inventory organization wise.

We have 3 Organizations, so while using Creating Requisitions based on  the Destination Organization, we need to create separate approval limits.

Ex: Inv Org- IN1  -- 0-10000$ Limit

                    IN2  -- 0-50000$ Limit

                    IN3  -- 0-25000$ Limit

I have created custom attribute to get the inventory org code and used this attribute in the conditions, and then created custom Approval Groups using the  Serial Numbers as 1,2,3 voting method as "Serial" .

After I created the Rules, when i try to create requisition system is validating only the 1 st Rule . when i change the Organization as IN2, IN3  system says no approvals found.
