Matching Model and Source Columns

When you create a model, the columns in each data source are saved as part of the
model definition.
If you reorder, add, delete, or rename the columns in any data source, you must
update the model by running the Modify Columns command.
For example, suppose your source file has columns named DATE, PRODUCT,
SALESPERSON, QTY_SOLD, and PRICE. The sales representatives are reorganized
into units, and a UNIT column is added to store this new transactional data. You
run the Modify Columns command to update your model.
For more information about the Modify Columns feature, see "Synchronizing
Columns with Your Data Source" on page 37.
