A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

• Built-In: You create and store the
  schema locally for this component only. Related topic: see
  Talend Studio
  
  User Guide.

• Repository: You have already created
  the schema and stored it in the Repository. You can reuse it in various projects and
  Job designs. Related topic: see
  Talend Studio
  
  User Guide.

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.

Enter the name of the input table between double quotation marks.

Specify the metadata mapping file for the database
to be used. The metadata mapping file is used for the data type conversion
between database and Java. For more information about the metadata mapping,
see the related documentation for Type mapping.

Note that this drop-down list is disabled, and by default, Mapping
SAP is selected and the SAP metadata mapping file is used.

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

The error message generated by the component when an error occurs. This
is an After variable and it returns a string.
