If you have the BI Publisher Template Builder installed, you can preview the template and subtemplate combination before uploading them to the BI Publisher catalog.
To test from your local environment, you must alter the import template syntax to enable the BI Publisher processor to locate the subtemplate file on a local directory. To test, enter the import template syntax as follows:
<?import:file:{local_template_path}?>
For example:
<?import:file:C:///Template_Directory/subtemplate_file.rtf?>
or for an XSL subtemplate file:
<?import:file:C:///Template_Directory/subtemplate_file.xsl?>
You can then select the Preview option in the Template Builder and the BI Publisher processor can locate the subtemplate and render it from your local environment.
Note that before you upload the primary template to the BI Publisher catalog, you must change the import syntax to point to the appropriate location in the catalog.
