Reliable way to identify negative gross / net pay employees without error message text?

Hi all,

We maintain a custom BI Publisher report that flags
employees with negative gross or negative net payments during payroll processing. The
report is provided to our Final Pay team during on-cycle processing.

How it works today:
We read pay_message_lines and identify impacted employees by matching the payroll error
message text, for example:

• "The employee has negative total gross payments. They need to be positive."
• "Total gross payments for an employee are negative."
• "The employee has negative total net payments. They need to be positive."

We have mapped these to seeded messages such as PAY_HPCM_GROSS_PAY_NEG and
