# tReplace Standard properties These properties are used to configure tReplace running in the Standard Job framework. The Standard tReplace component belongs to the Processing family. The component in this framework is available in all Talend products. ## Basic settings | Properties | Description | | --- | --- | | Schema and Edit
Schema |

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

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.
Two read-only columns, Value and Match are added to the output schema automatically.
Built-In: You create and store the schema locally for this component only.
Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

variable functions only if the Die on error checkbox is
cleared, if the component has this checkbox.
