ABAP OO Class Methods

IF_UG_R3_SERVICES SAP Interface - FIN Master Data: Services for mySAP ERP Access







IF_UG_R3_SERVICES is a standard SAP interface, see below for any documentation including details of methods, attributes, events etc. Interfaces are defined much the same as a class using the same transactions but act a bit like a template (in none OO terms). For example, a class would implement the interface and then inherit all of the methods etc from it. This provides a mechanism for unrelated objects to use a set of common behaviours and functionality.


You may have seen this already without knowing what it was, within SAP have you ever seen the method name prefixed by the name of an interface such as IF_UG_R3_SERVICES~METHOD_NAME . This means that the class has implemented an interface and that this method has been inherited from it.


For further relevant information about this interface enter IF_UG_R3_SERVICES into the relevant SAP transactions such as SE24, SE80. Also see the Resource section below to view other useful tips, screenshots, links and general information related to this SAP interface and its methods. Or even add your own for future reference



Methods of IF_UG_R3_SERVICES
