Hi,
First of all your question is wrong.
Sap Architecture is defined in such a manner that If all 3
layers come in a single system then that system is called
as Single System Landscape.In this manner we have 3 system
landscape and 4 system landscape.

Single System LandScape is defined as when all the 3 layers
come in a single system as below :

1) Presentation Layer
2)Application Layer
3) Data Layer

If all the above 3 layers come in a single system then that
system is called as Single System LandScape.

If 2 layers come in one system and another layer comes in
another system then that system is called as 2 System
Landscape

for example :one system will contain Presentation as well
as Application layer and 2 system will contain only Data
layer .

If all the 3 layers come in 3 different systems then that
system is defined as 3 system landscape.

The 4th layer is defined as if SAPAS layer in which one
will find InternetLayer along with these 3 layers for
communication between different locations and this layer is
called as 4 system landscape.

The Scenario you have mentioned like 1 dev,2 quality and 2
production is a 3 system landscape and it is not 5 system
landscape.

I have a requirement from the SD people wherein whenver one runs the tcode F-02 (Enter G/L account Policy : Header Data), they should not get the list of all acounts in the ACCOUNT field. But when i go to pfcg to check for restricting the list, i dont find any pertinet auth field for doing so. Isi t something that we can ( as Basis Admin) do or the ABAPpers to do. Maybe the ABAPpers have to program the screen where in they need to restrict the list options. If not so, lemme know the auth field that has to bet set if any.
