The Propagate command fills all the empty cells in the current field, leaving the previously filled cells untouched. The Propagate command propagates filled data cells into the empty data cells (if any) below them.
To illustrate, here is a database where the date was only entered for the first check written each day. For example, there were 13 checks writtin on January 1st, and another ten written on the 5th, and then another 3 written on the 12th. Using the Propagate command Panorama can automatically fill in the dates that were left blank.
You may find this illustration clearer for understanding how propagation works. The Propagate command starts from the top of the field and works its way down. Whereever it finds an empty spot, it fills it in with the last non-empty cell above.
The Propagate Up command performs the same operation upside down, propagating filled data cells into the empty data cells above them.
This command performs the exact inverse of the Propagate command. If the same value appears in two or more consecutive data cells, the Unpropagate command empties the second and subsequent data cells. Here is a database that has been sorted by city. Using the Unpropagate command eliminates all but the first entry for each city.
The Unpropagate Up command performs the same operation upside down, leaving the last of several duplicate values while clearing the others.
The Unpropagate command can be used to eliminate duplicate values in a database. The first step is to click on the field that contains the potentially duplicate values, for example Name or Company. If you want to eliminate duplicates over multiple fields (for example an entire address) you must create a new field and use the Manipulate Data dialog to combine the data into a single field.
