Column Headings property
This is where you specify translatable prompts for the column headers in Details mode, with a length up to 90 characters each. Normally, the column heading is derived from:
•The label provided in the query statement (NOT translatable, on some databases limited to 30 characters)
•The column prompt (limited to 30 characters)
•The column name (limited to 30 characters)
Using this property, you can overrule these prompts for some or all columns. You provide a list of prompts , separated by new lines. For any column where you do NOT wish to override the default, fill in a "-" only. For any column that has no overriding prompt specified, the default prompt is taken.
