Good day, everyone!

We have configured an several compensation plans with the following rules:

Plan 1 is restricted by personal contribution workflow (it can be initiated by employee and then should be approved by LM);

Plan 2 is restricted by administer individual compensation (can be initiated by CnB specialist and then should be approved by LM)

When employee initiated Plan 1, itworks correctly: approval notification is sent to LM and LM can edit compensation through edit button in approvals.

When Administrator initiate Plan 2, we have following issue: approval notification is sent to LM (this part is correct) and when LM clicks on "edit" button he only can see the white screen. Even when we add to Plan 2 workflow manage individual compensation, the issue still remains (even when manager can initiate this plan, he still could not edit it trough approval).
