Before we fix the mistake, you need to understand the beast. The PSA Interface Checker acts as a traffic cop between your local Dealership Management System (DMS) and the PSA Group’s central servers. It checks for three things:
The "scary mistake" usually appears when the checker finds a delta—a difference between what PSA thinks you have and what your local system thinks you have. psa interface checker scary mistake fix
Most "scary mistakes" are just timing errors. Before you touch anything, wait 15 minutes. The interface checker often has built-in retry logic that resolves 60% of errors automatically. Panic is what breaks the system. Before we fix the mistake, you need to understand the beast
The Interface Checker operates on a heuristic: "If a time entry references a Project ID that does not exist in the ERP master list, flag it as an orphan and attempt to resolve it." The "scary mistake" usually appears when the checker
The specific code change introduced a filtering error in the validation query.
The "Before" Logic (Simplified SQL):
-- Check if the Project ID exists in the valid list
SELECT t.entry_id
FROM time_logs t
LEFT JOIN projects p ON t.project_id = p.id
WHERE p.id IS NULL;
The Buggy "Patch" Logic:
-- Intended to exclude Shadow Projects (ID starts with 'INT-')
-- but the parenthesis placement inverted the logic.
SELECT t.entry_id
FROM time_logs t
LEFT JOIN projects p ON t.project_id = p.id
WHERE p.id IS NULL
OR p.id LIKE 'INT-%';
