From the Staging Data Browser in Talend MDM Web User Interface, you can simulate the validation of a staging data record and then determine how to make changes to the record to make it valid.

Prior to being saved to the master database, a staging data record has to go through a validation process, which involves checking the staging data record against the database schema, foreign key constraints, the data model validation rules defined in Talend Studio, and the Before-Saving process (if any) of the entity which the data record pertains to.

For more information about the validation rules and the Before-Saving process, see Talend Studio User Guide.


When you simulate the validation of a staging data record, make sure that the Job called by the Before-Saving process does not create new data or modify the existing data.

To simulate the validation of an existing staging data record, do the following:

  1. Follow the steps outlined in How to open a staging data record in an entity to open the staging data record of interest.

  2. In the [Staging Data Browser] page, click More... > Validate on the menu bar.

    A message box pops up, showing that the record is valid.

    If some record is not valid, the details about why the record is not valid will be displayed.

A REST API interface is also available for validating data records against the master storage. For more information, see Talend Help Center (
