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.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

Click Edit schema to make changes to the schema. If the
current schema is of the Repository type, three options are
available:

Built-in: The schema is created
and stored locally for this component only. Related topic: see
Talend Studio User
Guide.

Repository: The schema already
exists and is stored in the Repository, hence can be reused. Related
topic: see Talend Studio User
Guide.

Column as Measure

Select the column from the input stream which holds the Measure or
Text values.

Create element if not exist

Select this check box to create the element being processed if it
does not exist originally.

Save cube at process end

Select this check box to save the cube you have written the data
in at the end of this process.

Advanced settings

tStat
Catcher Statistics

Select this check box to collect log data at the component
level.

Global variables

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

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.

User Guide.
