Configuring Workspace Transport Packages 
A workspace transport package should not include initial content, so that it does not override initial content on the target system. To prevent including initial content in workspace transport packages, you need to configure the PCD location from which to import the workspaces.
This configuration requires restarting the portal. Therefore, to avoid an additional restart, we recommend performing the configuration before the installation of enterprise workspaces.

To exclude initial content from workspace transport packages:
Open the following properties file:
<Drive>:\usr\sap\<SID>\SYS\global\pcd\pcdStartup.properties
Enter the following key and value:
Key: Pcd.TransportApplication.ProtectedUrlPatterns.Custom
Value: pcd:portal_content/com.sap.pct/templates/workspaces/*
Note
If the key already exists in the file, add the value, separating it from the previous value with a comma.
Save the file.
Restart the J2EE server.
