To add a global branding logo and more predefined transactional attributes to the journal approval email notification, you should copy (or customize) and edit the layout template and the data model. The layout template is a file that defines the appearance and content of the notification, such as text, images, tables, or charts. The data model is a file that defines the data sources and queries that provide data for the notification, such as predefined transactional attributes. You can copy (or customize) and edit the layout template and the data model using Oracle Analytics Publisher reports. You do not need to copy (or customize) and edit the output type, as this is a setting that determines the format of the notification output, such as HTML or PDF. You do not need to copy (or customize) and edit the style template, as this is a file that defines the styles and formatting of the notification elements, such as fonts, colors, or margins. You do not need to copy (or customize) and edit the sub template, as this is a file that contains reusable content or logic that can be referenced by multiple layout templates. Reference: Oracle Financials Cloud: General Ledger 2022 Implementation Professional Objectives - Configure Workflow Approvals and Notifications 12
