WBS or "Work Breakdown Structure" describes the global structural layout of a project. In comparison to a graphical display of the project structure (which can be imported into Merlin, e.g. from a mind map), Merlin is responsible only for the structured display in the outline.

In the "File" menu you can access the "WBS Code Settings." Merlin will display a dialogue form in which you can define the structure of the WBS.

Prefix - Here you can enter a global prefix, which is used for the WBS code.

Level - The levels are numbered consecutively and define the outline level of the structure.

Sequence - Here you can select the form of the outline. The following forms are available:

• Numbers (this is also the default when nothing is defined)
• Lowercase letters
• Uppercase letters
• Lowercase roman numerals
• Uppercase roman numerals
• Numbers - spelled out

Example - In this section you can view an example of how the WBS code will be displayed.

In the Activity view and the Utilization view it is possible to activate the relevant column in the outline. In the Netplan view the WBS code can be activated to be displayed in a section of the Netplan boxes.
