Confused with S/4HANA 1511 on premise versions - SP01 vs. FPS01 ?

[joachimrees1]

There allready are some blogs trying to solve confusion about S/4HANA versions, like Still confused about the S/4 (On premise) versions and their differences ? .

Also, there is SAP S/4HANA 1511 Initial Release, Feature Pack 01&02 : What's NEW & What's NOT !! Advantage S4HANA 1...

There is one thing though, which still confuses me:

Is there a difference between a Support Package (SP) and a Feature Package Stack (FPS)?

I tend to say "yes" beacuse when things have different names, they should refere to different things;

But I'm more and more drawing the conclusion that they are the same!

For sure, there are currently 2 versions of S/4HANA 1511 on-premise available:

1. “SAP S/4HANA, on-premise edition 1511” ( http://help.sap.com/s4hana_op_1511 )  ( FPS 0 / Initial Shipment Stack)

2. “SAP S/4HANA, on-premise edition 1511 Feature Package Stack 01” ( http://help.sap.com/s4hana_op_1511_001 )

(Oh, this used to be known as "1602" as well, but that name is no longer used)

[Edit: 3. "SAP S/4HANA, on-premise edition 1511 Feature Package Stack 02" ( http://help.sap.com/s4hana_op_1511_002 ; )]

We started out with SAP S/4HANA, on-premise edition 1511.

The we applied (as far as I understand) a Service Pack (SP1), now our system looks like this:

So it clearly says "SP-Level" 0001 - but where can I see the FPS (Feature Package Stack) ?

Is it the same thing? I don't know!

So what S/4HANA 1511 on-premise release are you on? Do you know? (Or do you - like me - just think you know? 😉 )

Your feedback is most welcome!

[Edit: Now that everything is explained very nicely at SAP S/4HANA on premise edition: FPS versus SPS, I know that my system is a “SAP S/4HANA, on-premise edition 1511 Feature Package Stack 01”-System.

Formerley also know as "SAP S/4HANA, on-premise edition 1602"

(please note that the SAP Fiori apps reference library still uses that term!)

Edit 2016-04-15: I saw this fixed yesterday, so now the (lengthy but correct) term "SAP S/4HANA, on-premise edition 1511 Feature Package Stack 01" is used everywhere, as far as I can tell!
