BPM Requisition approvals are not working as per the Design

Summary

BPM Requisition approvals are not working as per the Design

Content

--> As per the Expectation and Design, if the Requisition is created with one line and enter the Project Information then approval hierarchy working fine.

--> If we don’t provide the project information ( DFF's at Requisition Distribution level) then Requisition will be rejected.
Issue:
If we create the Requisition with Two Lines and enter the Project information in only one line and fill blank in second line, even in this case approval hierarchy is generating but as per the Expectation, approval should not trigger since the Second line has no information.
