3823741 - Why didn't the expense report route to the Cost Object Approver for all of the cost objects on the report?

We are using a Level based Cost Object Approver workflow.  Additionally, we have some approvers who are Cost Object Approvers for more than one cost object. Sometimes the approver could be a Level 1 approver for one of the cost objects and a Level 2 approver for a different cost object.  

For example, the approver is the Level 1 approver for cost object A and is also the Level 2 approver for cost object B.

We noticed once the approver has approved the expenses for cost object A, (the one for which they are the Level 1 approver), the report doesn't route back to them again for approval for cost object B (the one for which they are the Level 2 approver). As a result, the approver never saw the expenses that were allocated to cost object B.

We noticed that when an approver is the Cost Object Approver for different levels on multiple cost objects on an expense report, the report only routes to them for one of the cost objects. , KBA , CON-EXP-ADM-WFL-WL , Workflow , Problem
