Usage Notes

• Replace REPLACE_WITH_RUN_ID with the strRunId generated by the Variable Bootstrap pattern (e.g., RUN-20260320-143022)
• Replace REPLACE_WITH_FLOW_NAME with a hard-coded literal string identifying your flow (e.g., $'''Invoice Processor''')
• strRunHeader produces a single pipe-delimited line suitable for logging to file, Dataverse, or console output
• Pairs directly with Run Finalizer — the header is written at flow start, the footer at flow end, creating a complete audit bracket
• COMPUTERNAME and USERNAME are standard Windows environment variables available on all machines; no admin rights required
• Use strRunHeader as the first entry written by Log Detail Writer so every log file begins with full execution context

Requirements

• Windows environment with COMPUTERNAME and USERNAME environment variables set (standard on all Windows machines)
• strRunId should already be initialized by the Variable Bootstrap pattern before this runs
• No external dependencies — uses only built-in PAD System and DateTime actions
• Flow must run in attended or unattended mode on a Windows machine (not cloud-only)
