Basic settings

Schema and Edit schema |
A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository. Two read-only columns, Value and Match, are added to the output schema automatically. Important: The data type defined in the schemas must be
consistent, ie., an integer can only be replaced by another integer using an
integer as a look up field. Values of one type cannot be replaced by values of
another type.

|
|
Built-in: The schema will be created and stored locally for this component only. For more information about a component schema in its Basic settings tab, see Basic settings tab. |
|
|
Repository: The schema already exists and is stored in the Repository, hence can be reused in various projects and Job designs. For more information about a component schema in its Basic settings tab, see Basic settings tab. |

Global Variables

Global Variables |
ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it. For more information about variables, see Using contexts and variables. |
