After creating the necessary XML files for your provider, use the configuration utility to load the XML files that you created for your provider with seed data into the Gateway database. When you install Primavera Gateway, the installer invokes the configuration utility that uses the XML files to load seed data into the Primavera Gateway database.
To customize or create your own provider, refer to the files in the P6, Gateway, and schema folders. Use the Gateway configuration utility or upload your customization.xml from the Configuration page in the Gateway user interface. For more details, refer to the Primavera Gateway Provider Customization Guide.
