Business document management is built on top of the ER framework and enables business users to edit business document templates by using Microsoft 365 service or appropriate Microsoft Office desktop application. Edits to the documents might include changing business document designs and adding placeholders for additional data without source code changes and new deployments. No knowledge of the ER framework is required to update templates of business documents.
Note:
Business users use the Electronic reporting (ER) framework to configure formats for outbound documents in accordance with the legal requirements of various countries/regions. Users can also define the dataflow to specify what application data is placed in generated documents. The ER framework generates outbound documents in Microsoft Office formats (Excel workbooks or Word documents) by using predefined templates.
