In purchase approval hierarchy, Current manager (X) has been replaced by another one (Y). But X is still in the HR roll. Now all the approval has to go to Y. Implemented Position Hiararchy setup. Now after reassinging it goes to Y but X names is appearing as approver. When we sobmit it goes to X first then routed to Y due to vocation rule. How can this be changed so that the PO directly goes to Y not thro X. Both are listed as Managers by position.
