Hi Yogesh,
I believe that you have only one WBS at Level 1. If yes, then settle the project to PSG (Profitably Segment) to level 1 WBS and all WBS's elements other than Level 1 must be settled to its immediate prefix WBS Element within the organisation structure.
Try this scenario and also discuss the same with your FI/CO consultant.
