Modify stage in DataStage

Modify stage

The Modify stage alters the record schema of its input data set. The modified data set is then output. You can drop or keep columns from the schema, or change the type of a column.

The Modify stage is a processing stage. It can have a single input link and a single output link.

The stage editor has three tabs:

  • Stage. This is always present and is used to specify general information about the stage.
  • Input. This is where you specify details about the input link.
  • Output. This is where you specify details about the modified data being output from the stage.
