# Steps supporting metadata injection The ETL Metadata Injection step inserts metadata into your template transformation through a step that supports metadata injection. See the [ETL metadata injection](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/etl-metadata-injection.md) article for details on how metadata is injected or if you are not familiar with the term "template transformation". The following table specifies which steps contain fields supporting metadata injection: | Step | Version Introduced | Fields Supporting Metadata Injection | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [Add XML](http://wiki.pentaho.com/display/EAI/Add+XML) | 7.0 | All fields | | [Add a Checksum](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/add-a-checksum.md) | 8.2 | All fields | | [Annotate Stream](/pdia-data-integration/10.2-data-integration/advanced-topics-pentaho-data-integration-overview/work-with-the-streamlined-data-refinery/use-the-streamlined-data-refinery/building-blocks-for-the-sdr/using-the-annotate-stream-step.md) | 7.0 | All fields | | [AMQP Consumer](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/amqp-consumer.md) | 8.2 | All fields | | [AMQP Producer](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/amqp-producer.md) | 8.2 | All fields | | [Append Streams](http://wiki.pentaho.com/display/EAI/Append+streams) | 7.0 | All fields | | [Avro Input](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/avro-input.md) | 7.0 | All fields | | [Avro Output](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/avro-output.md) | 8.0 | All fields | | [Combination Lookup / Update](http://wiki.pentaho.com/display/EAI/Combination+lookup-update) | 7.0 | All fields | | [Concat Fields](http://wiki.pentaho.com/display/EAI/Concat+Fields) | 5.1 | All fields | | [Copybook Input](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/copybook-input-pdi-step.md) | 9.0 | All fields | | [CouchDB Input](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/couchdb-input.md) | 7.0 | All fields | | [CSV File Input](https://github.com/pentaho/documentation/blob/main/PDIA/10.2/PDI/Transformation%20steps/PDI%20transformation%20steps%20reference%20\(overview\)/CSV%20File%20Input=GUID-5EE50684-82FB-4EB1-B25C-3D9345B1300A=3=en=.md) | 4.1 | See [CSV File Input](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/csv-file-input.md) for a list of supported fields | | [Data Grid](http://wiki.pentaho.com/display/EAI/Data+Grid) | 5.1 | All fields | | [Data Validator](http://wiki.pentaho.com/display/EAI/Data+Validator) | 7.0 | All fields | | [Delete](/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/delete-step-pdi.md) | 9.0 | All fields | | [Dimension Lookup-Update](http://wiki.pentaho.com/display/EAI/Dimension+Lookup-Update) | 7.1 | All fields | | [ETL metadata injection](https://github.com/pentaho/documentation/blob/main/PDIA/10.2/PDI/Transformation%20steps/PDI%20transformation%20steps%20reference%20\(overview\)/ETL%20metadata%20injection=GUID-DFD39FB2-F48B-46E8-96F6-62F905AF7F3B=3=en=.md) | 7.0 | All fields.
