Central components of SAPforms.

SAPforms consists of several autonomous Visual Basic classes each of which is implemented by a plug-in. There are three types of plug-in, each of which contains a defined ActiveX interface.

All of the form and SAP-specific data operations within a form are carried out by the plug-ins. The SAPforms Designer uses plug-ins to communicate with the form and the R/3 System. From the perspective of the forms programmer, the plug-ins are objects whose properties and methods can be used to manipulate the forms.
