R/3 Architecture

 

Architecture à Steps to Perform

From this architecture and from the object hierarchy of the Function OCX and of the Table View OCX, the following steps can be derived:

The OLE client application communicates with the Function OCX via the OLE2 Automation interface. This requires

  1. Creating a Function OCX basic object as a container for explicit function objects in the client application.
  2.  

    This container contains objects for the connection, for function calls or parameter definitions, and for handling return values.

  3. Creating a table object.
  4. Connecting to the R/3 system.
  5. Creating a specific function object for defining the values for export parameters and tables.
  6. Calling the function.
  7. The application server executes the remote calls and transports the R/3 data to the OLE client.
  8. Adding the Table View to the table object and displaying the data.
  9. Disconnecting from R/3.
