List of Certified HR-PDC Partners

Hello fellow SCN members,

I am trying to locate List of Certified HR-PDC Partners.  Not able to do so...  I see different categories of partners and various buttons "Find this type of partner", etc.  However, I am not sure where I can look at all the partners by a specific integration scenario (namely HR-PDC for clock-in and clock-out).

Lastly, this page SAP ECC - Plant Data Collection - Time, Attendance and Employee Expenditures (HR-PDC) links to an official document on HR-PDC from SAP which 17 years old http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/40bceb90-0201-0010-7297-d5e11f35743f?overridelayout=t… ! :-)  I can't believe there has not been an update to the HR-PDC since version SAP HR 4.5. 

Thanks in advance,

Alex
