The Ascending property on the SORT gets lost – PB Docs 2022

Phenomenon

If you add an “Ascending” option to the SORT script, this option
gets lost.

Scenario

Do a SORT() to a DataWindow like follows:

This will return ls_sort = “COLUMN_NAME” without the “A” for
Ascending at the end.

Workaround

Use only lower case letters on the SORT condition. Like
follows:

This should return ls_sort = “column_name a” without loosing the
“A” for Ascending.
