Task Data View (Magic xpa 4.x)
Each Magic xpa task works with a set of records and their variables that you select from the application database. These variables, whether selected from the Main Source or from a linked table, are the task’s Column variables. In addition, you may define computed variables that exist for the duration of the task’s execution. These are the task’s Virtual variables or Parameters. Column and Virtual variables, and passing Parameters together constitute the task’s logical record. The set of logical records selected from the Main Source and linked tables in accordance with the task’s range rules constitutes the task’s data view.
All of a task’s variables – column, virtual, and passing parameters – are included in the task’s Variable list. Each variable in the list is assigned a letter code. Whenever you want to refer to a variable in a task, you use this letter code. A subtask’s variable list includes all the variables selected by its parent.
