Split Subrecord Stage
The Split Subrecord stage separates an input subrecord field into a set of top-level vector columns.
The Split Subrecord stage can have a single input link and a single output link.
The stage creates one new vector column for each
element of the original subrecord. That is, each top-level vector
column that is created has the same number of elements as the subrecord
from which it was created. The stage outputs columns of the same name
and data type as those of the columns that comprise the subrecord. 
The Make Subrecord stage performs the inverse operation
(see , "Make
Subrecord Stage.")
The stage editor has three pages:
- Stage Page. This is always present and is used to specify general information about the stage.
- Input Page. This is where you specify the details about the single input set from which you are selecting records.
- Output Page. This is where you specify details about the processed data being output from the stage.
