You have
added columns and you need to determine the scope of these additions.
Select one of the following scenarios:
-
No propagation: Adding column changes
to the output of a single transformation in a job
-
Automatic propagation: Automatically
adding column changes to tables in a specified direction
-
Manual propagation: Manually controlling
the addition of column changes in specified paths and directions
Note that
you can propagate column changes only in the context of a job. If
you add column changes in the properties window for a table from a
tree or a folder, the propagate and mapping options that you see on
the
Mappings tab in a job are not available.
In that case, you must remember to map and propagate the column changes
when you later use the altered table in a job. Therefore, it is generally
more efficient to make and propagate your columns directly in the
jobs where you need them.
