1. Review Business Requirements & Write Functional Specification
The first part of any ABAP development project begin with meeting the end users or business experts and understand the business requirements that need to be implemented in the SAP system during the realization phase. A best approach is to conduct workshops to gather all the business requirements. Make sure that if any SAP function consultants are involved than they are in the meetings as well. After all the business requirements are collected, either a SAP functional consultant or business expert will write a detailed functional specification. Review the functional specification until the document has all the details, different business scenarios and expected goals clearly defined. A well defined functional specification should contain UML diagrams and test case scenarios. It is important to have an official signoff on the functional specification before continuing with design and development.
2. Review ABAP Development Standards
In ideal case, your SAP Project Lead or ABAP Development Manager should have created a programming standards and guidelines document. Review this document so that you follow the naming conventions for function modules, classes, dictionary objects, software components, name spaces and proxies (if using SAP XI / PI), program input/output parameters, etc just to name a few. Following the guideline for the project helps maintain a consistent coding approach and also helps other functional and technical analysts to read and debug your code. ABAP objects naming should begin with Z if it will be migrated to SAP production system and Y if it will not be migrated into the production system.
