Definition

A port implements the inport or outport of a CHIP.

The port name can contain alphanumeric characters and the special character underscore (_). But it must not start with a numeral.

Use

Web Dynpro CHIPs and their ports are used in Page Builder to loosely couple Web Dynpro components with one another.

Dependencies

Each method of the interface controller of the Web Dynpro component that the CHIP is based on can function as a CHIP inport that fulfils the following conditions:

  • It has a maximum of one mandatory importing parameter. The parameter type must be a structure defined in the Data Dictionary or a table type of such a structure.
  • It must not have any mandatory changing parameters.
  • It can have any number of optional, exporting, or returning parameters.
  • If the method does not have an importing parameter, it can be used as an inport with each optional parameter, whereby the condition for the parameter type mentioned above must be fulfilled.

Similarly each event of the interface controller of the Web Dynpro component can be used as a CHIP outport provided it meets the conditions described above for methods.
