## How to Create a Decision Table

| ### What to do:
| As a prerequisite for this example, the DocuLogicModel must have been created as described in "How to Create a Logic Model". Additionally, you should have defined the DCU application as described in "How to define application Types".
| Open the Logic Models/Procedures form from the Manager > Macro > LogiView > Logic Models menu or click the button .
| Switch to Insert mode with the button .
| Select DocuLogicModel from the Logic Model field menu.
| Enter DocuDT as decision table name in the Name field.
| In order to prevent confusion with LogiView commands or functions, logic model names should contain capital letters.
| Enter Decision table for documentation in the Comment field.
| Select T - Decision Table in the Processing Type (Type) field.
| Click the Usage (Use) field.
| Click the button . The selection menu is opened.
| Select the DCU | Documentation entry and press enter to save it.
| To save the entry click the button .
| The Version, Time in memory if not used, Decision Table / Procedure ID (Number), Progress Indicator (PI), and Current Decision Table/Procedure (C) fields are filled in automatically. For performance reasons, the Time in memory if not used field value may be edited. (This value defines for how long "unused" decision tables / procedures are kept in the main memory.) The higher this value, the longer the decision table / procedure will remain in the main memory before it is deleted.
| The mask should now look as follows:
