Requisition Approval mapping set with reject rule and multiple lines

Summary:

Hi,

I created mapping set using cost center.

The data set is configured for few cost centers, so a requisition could include a not configured cost center.

I configured 2 rules in FSM.

Rule-1: Priority MEDIUM: Mapped Approval Attribute X is not blank with Action=Route Using Single Approver, Mapped Approval Attribute X

Rule-2: Priority HIGHER: Mapped Approval Attribute X is blank with Action=REJECTED

I created a requisition with 2 lines.

Line-1 where the cost center exists in the mapping data set. Then return a value as APPROVERS

Line-2 where the cost center does not exist in the mapping data set. So, I suppose there is no value returned.
