Injecting metadata into the ETL Metadata Injection step

For injecting metadata into the ETL Metadata Injection step itself, the following exceptions apply:

• To inject a method for how to specify a field (such as by FILENAME, REPOSITORY_BY_NAME, or REPOSITORY_BY_REFERENCE), set a TRANS_SPECIFICATION_METHOD constant to the field of an input step. You can then map the field as a source to the TRANS_SPECIFICATION_METHOD constant in the ETL Metadata Injection step.

• The target field for the ETL Metadata Injection step inserting the metadata into the original injection is defined by [GROUP NAME].[FIELD NAME]. For example, if the GROUP NAME is 'OUTPUT_FIELDS' and the FIELD NAME is 'OUTPUT_FIELDNAME', you would set the target field to 'OUTPUT_FIELDS.OUTPUT_FIELDNAME'.
