To modify the journal approval notification, you need to copy (or customize) and edit the layout

template and the data model of the Analytics Publisher report. The layout template defines the

appearance and content of the notification, such as the text, fields, tables, and images. The data

model defines the data sources and queries that provide the data for the notification, such as the

journal attributes, amounts, and statuses. You can use Template Builder for Word to edit the layout

template and Analytics Publisher to edit the data model. You also need to download the Workflow

Notification Subtemplate, which is a common subtemplate that contains the header and footer of

the notification. You can preview the modified notification using the subtemplate and the data

model. Reference:
