PO approval workflow

[Nicholas Brand]

A quick question...

We have a PO approval workflow using business object BUS2012.
It has one triggering event: 'SIGNIFICANTLYCHANGED'.
The relevant binding between the event container and workflow container is:
'_EVT_CREATOR' ==> '_WF_INITIATOR'
Fairly standard.

If User-A creates a PO it is workflowed to User-B for approval.
In the event log and workflow log the event creator and workflow initiator
are both shown as User-A.
User-B approves and releases the PO and the workflow completes.
This is all as it should be.

Now, if User-C significantly changes the PO so that a new release strategy
is required, the workflow is re-triggered.
In the event log the event creator (for the new workflow) is correctly
shown as User-C.
In the workflow log you'd expect the workflow container element
'_WF_INITIATOR' to be equal to the '_EVT_CREATOR' value (User-C) - but it
ain't!
Instead the workflow container element '_WF_INITIATOR' is still shown as
User-A.

In other words, the user who first creates the PO is entered in the
workflow container element '_WF_INITIATOR' even for subsequent workflows
against the same PO.

At a guess it seems like an error in the function module that populates the
_WF_INITIATOR workflow container element.

Any clues out there? Is there an OSS note for this?

BTW we're on v4.6c
