The ne operator selects items whose
specified attribute name contains a value not equal to the specified
with attr.name ne "valuestring"
select invoices with amount.due ne "0"
select invoices with amount.due # "0"
Note: When using an ADI with an mt processing code, a null value is converted
to zero before testing for equality or inequality. Therefore, ADI = “” will find nothing and ADI
# “” will return everything. This only affects “equal” or “not equal”. “Less than or equal”,
“Greater than or equal” and others are not affected.
