If you used the Open Template dialog to connect to BI Publisher, and load the data to the Template Builder, or if you downloaded an existing template from the BI Publisher catalog, then you can upload the new or updated layout back to the report definition on the server.
See Working in Connected Mode.
If you downloaded an existing template and want to upload the modifications to the template, then select Upload Template from the Oracle BI Publisher menu.
If this is a new template for the report definition, then use the Upload Template As option to upload the layout to the report definition on the server. Also use this option to upload modifications to an existing template under a different name.
