D365FO - Start hierarchy approval with specific worker

There are times when clients want to start hierarchy approval from a specific worker and not from the one who initiated the workflow and then traverse up the hierarchy.

Scenario:

• Invoices are coming from third-party into FinOps and creating tax invoice registers
• Setting the Approved by field at tax invoice register line level
• AP Clerk/Administrator assigns these invoices to correct worker for approval

So, in the above scenario, the AP clerk initiated the workflow but the workflow will not go his/her line manager for approval instead it will be assigned to the owner (approved by) of the invoice.

This is what we want to achieve - add a new Start from

This Start from list get populated through getSupportedDataType() in  class WorkflowHierarchyProviderHelper

Create a new event handler class and subscribe to the delegate as shown below.

P.S. WFOwner is the custom created EDT.

class ECL_WorkflowHierarchyProviderHelperEventHandler

{

    [SubscribesTo(classstr(WorkflowHierarchyProviderHelper), delegatestr(WorkflowHierarchyProviderHelper, addAdditonalSupportedDataTypesDelegate))]

    static void addAdditonalSupportedDataTypesDelegate(Set _supportedDataTypes)

    {

        _supportedDataTypes.add(extendedTypeStr(WFOwner));

    }

}

Add a new field on LedgerJournalTable and assign the WFOwner EDT to it. LedgerJournalTable is for reference as the above change is implemented for vendor invoice approval.
