Hello,

We're looking for moving the Approval Delegations from the BPM console to the Employee Self Service page "Roles and Delegations".

We're testing the Purchasing-related categories, in the Approval Delegations section at the bottom of the page : HtCatgry.PurchaseRequisitions, HtCatgry.Purchasing1 and HtCatgry.Purchasing2 - based on "Purchase" appearing in the category names.

The delegation is not applied: when a Requisition is done, the approver receives the Approval Notification, not the Delegated Person.

We tried with only one active rule for each category, as well as 3 rules active at the same time (one for each category), no difference.
