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.

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

• View schema: choose this option to view the
  schema only.

• Change to built-in property: choose this
  option to change the schema to Built-in for
  local changes.

• Update repository connection: choose this
  option to change the schema stored in the repository and decide whether to propagate
  the changes to all the Jobs upon completion. If you just want to propagate the
  changes to the current Job, you can select No
  upon completion and choose this schema metadata again in the [Repository Content] window.

Built-in: No property data stored
centrally.

Repository: Select the repository
file where the properties are stored. The fields that follow are
completed automatically using the data retrieved.

Filename

The name of and path of the input file to be processed, which you
can enter manually between double quotes or browse and select by
clicking the […] button.

Mode

Read the file as a string: The
content of the file is read as a string.

Read the file as a bytes array:
The content of the file is read as a bytes
array.

Stream the file: As soon as the
first character is entered in the source file, it is read
immediately.

Encoding

If you are using the Read the file as a
string mode, select the encoding type from the list
or select Custom and define it
manually.

Die on error

Select this check box to stop the execution of the Job when an
error occurs. Clear the check box to skip the row on error and
complete the process for error-free rows. If needed, you can collect
the rows on error using a Row >
Reject link.

To catch the FileNotFoundException, you also need to
select this check box.

tStatCatcher Statistics

Select this check box to gather the processing metadata at the Job
level as well as at each component level.

Global Variables

FILENAME_PATH: the path of the input file. This is an
After variable and it returns a string.

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.
