| Schema and Edit<br>Schema | <ul> <li> <p>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 <span>Built-in</span> or stored remotely in the									<span>Repository</span>.</p> <p>Click <span>Edit        schema</span> to make changes to the schema. If the current schema is of the <span>Repository</span> type, three options are available:</p> <ul> <li> <p> <span>View schema</span>: choose this                option to view the schema only.</p> </li> <li> <p> <span>Change to built-in property</span>:                choose this option to change the schema to <span>Built-in</span> for local changes.</p> </li> <li> <p> <span>Update repository connection</span>:                choose this option to change the schema stored in the repository and decide whether                to propagate the changes to all the Jobs upon completion.</p> <p>If you just want to                propagate the changes to the current Job, you can select <span>No</span> upon completion and choose this schema metadata                again in the <span>Repository Content</span>                window.</p> </li> </ul> <p> Click <span>Sync columns</span> to retrieve								the schema from the previous component in the Job.</p> </li> <li> <p> <span>Built-in</span>: You create the schema								and store it locally for the relevant component. For more information about a component schema in its <span>Basic settings</span> tab, see <a href="https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/basic-settings-tab" target="_blank">Basic settings tab</a>.</p> </li> <li> <p> <span>Repository</span>: The schema already								exists and is stored in the Repository, hence can be reused in								various projects and Job flowcharts.
