Definition

You can use set/get parameters to predefine values in screen fields. In the Drag&Relate environment, set/get parameters fulfill two tasks:

  • Completion of keys
    • If the business object key consists of more than one field, the non- identifying key fields must be supplemented by set/get parameters. The prerequisite for this is that the application has set these parameters, otherwise the system cannot generate the link.

Example: The key for the cost center object consists of the fields Controlling area and Cost center. The identifying data element is Cost center and the content of the key field is identical to the field content of the screen field at runtime, the system gets the controlling area from the set/get parameter CAC.

  • Setting parameters for services
    • When you start a service (for example, a transaction), the system sets the set/get parameters that were assigned to the key fields. If the start screen of the transaction that is started contains these parameters as get parameters, no further parameters need to be defined. If you can set enough parameters for the transaction using set/get parameters, you should give preference to this procedure, instead of explicitly linking key fields to input fields, since, in this case, the system can start the transaction using a simple call transaction (without batch input).
