Prototype Data Type
Figure 1: Convert Prototype Data Type into concrete Data Type
A Prototype Data Type is a placeholder for a Parameter of a yet undefined Data Type, which is used for throughout Rapid Prototyping (prototypical modeling of a Workflow). A Service that uses Prototype Data Types is not deployable and thus not executable. Prototype Data Types are the counterpart of Prototype Services in terms of Rapid Prototyping.
Prototype Data Types can be recognized by the striped background area 
. Parameters from concrete Data Types have a plain white background 
.
To convert such a prototypical Data Type into a concrete one, select Convert into Data Type from its context menu. With the prompting mask (cf. fig. 1), you can specify the Label, while the Short Name will be deduced from the Label automatically. The Path should have the structure Department.Section.FunctionGroup.
Proceeding by clicking Create converts the selected Data Type into a concrete Data Type that does not yet contain any Member Variables. Then open the newly created Data Type for editing (see Create a Data Type for more details).
Please note: If there are more Prototype Data Types in a Workflow with the same name, converting one will not automatically replace the other ones too. This has to be done manually. To improve this approach, a Prototype Data Type should be converted as soon as possible to be able to use it furthermore (Reusing Data Types during Modeling).
