BY-EXP is a modifier that first separates values in a MultiValued attribute and then sorts them in ascending order. EXP stands for exploded, meaning that each value in the MultiValued attribute is sorted separately.
Format
|
BY-EXP attribute [BY-EXP attribute ...] |
Example
This example sorts orders by last name, then sorts the MultiValued item TITLE. The BREAK-ON modifier separates the report by LAST-NAME:
|
>SORT ORDERS BY LAST-NAME BY-EXP TITLE BREAK-ON LAST-NAME TITLE |

If the BY modifier had been used in place of BY-EXP, TITLE would have been sorted by the first title of each order only. The remaining titles would not have been sorted.
