Is mandatory to understand and create a Policy/Strategy for the SLD in your company. SLD have
different synchronization mechanics:
• Fully automatic synchronization
Only provide in NW 7.1 or higher.
• Automatic Message Forwarding
Using Data Suppliers.
• Data Export/Import.
• Using CTS.
In NW7.0 and complex.
Define new Data Suppliers
If you want to update the SLD Information between 2 SLD, you can use the SLD Data supplier.
In http:<sld_host>:5<sysnr>00/SLD , AdministrationData Suppliers
Click in Add SLD..
Add the Connection parameter and Save
Now you can see the new SLD connection.
You can check in the SLD Log if the new connection start the replication process.(In this sample
don’t work because we use difference CIM Version ;-)).
Cleanup old systems
Every system in the landscape send all the technical Information to the SLD every 720 minutes,
this is the standard time defined by sap.
If you don’t charge manually information in SLD is a good practice clean the SLD Information to
control the status of the updates in SLD.
Logon to SLD and list all the system, sort by Last Update. You can see few system with old data.
