When DataWindow Designer generates the basic DataWindow object, it defines whether the data is updatable by default as follows:
If the DataWindow object contains columns from a single table and includes that table's key columns, DataWindow Designer defines all columns as updatable and specifies a nonzero tab order for each column, allowing users to tab to the columns.
If the DataWindow object contains columns from two or more tables or from a view, DataWindow Designer defines all columns as not being updatable and sets all tab orders to zero, preventing users from tabbing to them.
You can accept the default settings or modify the update characteristics for a DataWindow object.
