SEO_CLASS_CREATE_COMPLETE函数模块用于在SAP零碎中创立一个残缺的SAP类。在SAP ABAP中，类是面向对象编程的根本构建块，它容许开发者将数据和行为组织到一个繁多的实体中。SAP的类通常用于形容业务对象、数据结构和业务逻辑，以实现灵活性和可维护性。
SEO_CLASS_CREATE_COMPLETE函数模块的主要用途包含：
- 创立类： 通过
SEO_CLASS_CREATE_COMPLETE，开发者能够在SAP零碎中创立一个新的ABAP类。这个类能够是一个一般的类，也能够是一个异样类、单例类或接口类。 - 定义属性和办法： 在创立类时，能够应用该函数模块来定义类的属性（成员变量）和办法。属性能够是公共的、受爱护的或公有的，办法能够是实例办法或类办法。
- 处理事件： 除了属性和办法，
SAP ABAP类还能够处理事件。通过SEO_CLASS_CREATE_COMPLETE，能够为类增加事件处理程序，以响应特定的事件。 - 实现接口： 如果一个类须要实现一个或多个接口，
SEO_CLASS_CREATE_COMPLETE也能够用于为类增加接口的实现。 - 定义继承关系：
SAP ABAP反对继承关系，容许一个类继承另一个类的属性和办法。通过SEO_CLASS_CREATE_COMPLETE，能够定义类之间的继承关系。
本文介绍应用下列 ABAP Function Module 生成新的 ABAP 类的办法。
