Symptom
As described in Planning Guide for System Landscape Directory's section Data Distribution Options, there are three options to synchronize data between two or more SLDs:

Full automatic synchronization (Unidirectional or Bidirectional Sync);
Automatic forwarding of data suppliers (Bridge Forwarding);
Manual data export and import functions can be combined with the transport of SLD objects with the enhanced Change and Transport Sysmtes (CTS+).
This KBA will provide details about how to set a Content Full Automatic Synchronization.

Environment
Java SAP system based on SAP NetWeaver 7.1 or higher;
System Landscape Directory;
Operating system independent;
Database independent;
Resolution
Warning: Full Automatic Sync only works for Systems based on SAP NetWeaver 7.1 or higher. If the system is running in a lower release, use Brigde Forwarding option instead (More details in Post-Installation Guide's section 'Configuring the SLD Bridge.
The following steps show how to set the Full Automatic Sync between the SLDs.

For Unidirectional Synchronization, the following steps must be done only in the target SLD (where all content must be stored).
For Bidrectional Synchronization, the following steps must be done in both SLDs.
To synchronize one SLD to another one, follow the steps below. This steps will set the source SLD to get the data from:

Start SLD and choose Administration > Content > Synchronization;
In Maintain SLD content synchronization screen, click button Add:

In Content Synchronization Wizard, choose option Remote to field Source and click button Next:

In Enter the connection information from source (remote) SLD screen, provide host name, user and password of Souce SLD (where the data is coming from) and then click Next button. Make sure the Souce User contains UME Role / User Group SAP_SLD_CONTENT_SYNC (for further details, please read Post-Installation Guide's section Configuring SLD Security Roles):
