Install SAP GUI on the central instance host
Preparing for Installation in Windows
You must use NTFS for an SAP system installation
Update Dynamic Link Libraries (r3dllins.exe)

Reducing the Size of the File Cache
Start -- Settings -- Control Panel -- Network and Dialup
Connections-- Local Area Connections
When the Maximize data throughput for network applications
option is selected, the windows
file cache is reduced in size so that application server
software, such as SAP system, has
more resources available. This also decrease the time needed
for the installation, especially for
the database import

For the installation, you need a user with administration
rights.

You need to prepare one host in SAP ERP Central Component
for the role of transport host.
Map the IP address of the transport host to the
SAPTRANSHOST, you can map the IP address to
the SAPTRANSHOST alias in the Hosts file

Goto <Drive>:\WINNT\system32\drivers\etc
Open the Hosts file with an editor and add the line:

<IP_ADDRESS> <fully qualified hostname> <hostname> SAPTRANSHOST
e.g., 
10.22.8.00  twdf0000.wdf.sap.corp  twdf0000 SAPTRANSHOST

Preparing for the SAPinst Installation in Windows
Install Java Development Kit on every host on which you want
to run SAPinst
Clean up the JDK\ext directory
Set JAVA_HOME environment
Add %JAVA_HOME%\bin to your system path
Install SAPinst
Start SAPinst from the SAP Master DVD, Double-click
sapinst.exe from in the directory
<G:\Setup\SAP_Installation_Master_ECC_ORA\IM1\SAPINST\NT\I386>

After client export, Import the client export requests into
the target client with TMS. Log on to the target client and
activate post-import processing with SCC7

Export the client in Background processing with SCC8

To perform a client export, follow these steps:

1. Log on to the source client. From the SAP initial screen,
choose transaction SCC8 (Client Export). Select the data to
be copied using a profile.

2. Indicate the target system to which the client will be
copied. The target system must be defined in TMS as part of
the transport domain.

3. Begin the client export. Because copying is a lengthy
process, use scheduled background processing.

You can check the status of the export with the transaction SE01

Import the client export requests into the target client
with TMS

Log on to the target client and activate post-import
processing with SCC7

To display client transport logs use the Transport Organizer
(transaction SE09)

Verify that database resources are sufficient
Monitor a Client Copy with SCC3
Restart a terminated run if necessary
Check tables using database utility or SQL tools
Tables not in development class $TMP

If any case, you discover an unexplained cancellation or
error, check
1.) Copy log (transaction SCC3)
2.) SysLog (transaction SM21)
3.) Dump analysis (transaction ST22)
4.) Job overview (transaction SM37)
5.) and possible spool (transaction SP02)

Create New client with transaction SCC4, Log on to your new
client e.g, 200 with user SAP* and password pass.Choose
transaction SCCL , Select u r source client e.g, 100. For
the selected profile, choose SAP_USER choose Enter. 

Create and schedule the job in background, the log is
displayed in SCC3

To use the compare function, from the SAP systems initial
screen, choose transaction SCU0. The compare function
enables you to compare and adjust the contents of a table or
view in two different clients, using RFC connections. This
is especially useful after an upgrade or language import.

The objects that can be adjusted are some of the tables and
views that can be maintained using transaction SM30. All
other objects can only be compared.

Set client option: Protection level : 2
No overwriting, no external availability
All production clients should use this setting.
