How to create custom WMS label field with NVL command
While trying to create custom field for label printing in Oracle WMS I faced issue with NULL value. If query returns NULL value, then label not printing and label request has Warning status.
However if I try to enhance my custom field SQL command with NVL, it doesn't let me telling
"Please select only one column in the supplied custom SQL Query"
Is it bug? Please advise how to work around this?
Thanks in advance
