The document provides guidance for using Function Specification templates in Microsoft Word to specify ABAP-based custom developments on SAP systems. Different templates are provided for different types of developments like workflows, reports, interfaces, conversions, enhancements, and forms. The templates prompt the user to replace guidance text in red or curly brackets with their own text. Headers will automatically populate the workstream and development details from the cover page. Users can save the templates to their Custom Office Templates folder to create new documents directly from the templates in Word.
