Property Type

Either Built-in or Repository.

Built-in: No property data stored
centrally.

tMDMTriggerOutput is expected to
use this option in order to apply the default read-only schema.
MDM_message is the only column
of this schema.

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

As tMDMTriggerOutput provides a
fixed read-only schema, you are expected to use the Built-in option.

Schema and Edit
Schema

A schema is a row description, it defines the number of fields
that will be processed and passed on to the next component. The
schema is either built-in or remote 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: The schema will be
created and stored for this component only. Related Topic: see

Talend Studio User
Guide.

This is the default option for tMDMTriggerOutput. With this option, the read-only
schema is used to deal with the XML-format MDM message.

Repository: The schema already
exists and is stored in the repository. You can reuse it in various
projects and jobs. Related Topic: see
Talend Studio User Guide.

As tMDMTriggerOutput provides a
fixed read-only schema, you are expected to use the Built-in option.

tStatCatcher Statistics

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

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 further information about variables, see
Talend Studio

User Guide.

Usage rule

Use this component as an end component. It needs an input
flow.

To send message to MDM, you need to deploy the Job using this
component on your MDM server and generate the corresponding trigger
and process to invoke this Job in MDM.

For further information about how to deploy a Job onto MDM server
and how to generate a trigger or a process, see
