The Extension Layer enables customer-specific add ons for each application module, also available to software developers of the customer, empowered by the user exit technologyof the Application Layer.
Customer-specific objects in the extension layer are generally not overwritten during service deliveries. Objects in the Extension Layer, that had been created on special request by the customer, can be overwritten by outbound deliveries as required.
NOTE: In very rare cases, it may be necessary to adapt software objects in the Extension Layer to new interfaces of the Application Layer. This is the case, when changes in the adjoining software systems make it necessary to adapt the contents and / or formats of the interfaces between Work Line Connect® and these systems and to pass these new interfaces to objects in the Extension Layer continue.
In such a case, the delivery of modules of the Application Layer takes place after prior notice of the effects and any necessary adjustments of customer objects in the Extension Layer.
