Weekly Timesheet Report + Pending Submissions Workflow

Overview

This workflow automates the entire weekly timesheet reporting cycle by integrating Salesforce, OpenAI, Gmail, and n8n. It retrieves employee timesheets for the previous week, identifies which were submitted or not, summarizes all line-item activities using OpenAI, and delivers a consolidated, manager-ready summary that mirrors the final email output.

The workflow eliminates manual checking, reduces repeated follow-ups, and ensures leadership receives an accurate, structured, and consistent weekly report.

Workflow Structure

Data Source: Salesforce DBT Timesheet App

This workflow requires the Digital Biz Tech – Simple Timesheet managed package to be installed in Salesforce.

Install the Timesheet App: https://appexchange.salesforce.com/appxListingDetail?listingId=a077704c-2e99-4653-8bde-d32e1fafd8c6

The workflow retrieves:

• dbt__Timesheet__c — weekly timesheet records
• dbt__Timesheet_Line_Item__c — project and activity entries
• dbt__Employee__c — employee reference and metadata
• Billable, non-billable, and absence hour details
• Attendance information

These combined objects form the complete dataset used for both submitted and pending sections.

Trigger

Weekly n8n Schedule Trigger — runs once every week.

Submitted Path

Retrieve submitted timesheets → Fetch line items → Convert to HTML → OpenAI summary → Merge with employee details.

Pending Path

Identify “New” timesheets → Fetch employee details → Generate pending submission list.

Final Output

Merge both paths → Build formatted report → Gmail sends weekly email to managers.

Detailed Node-by-Node Explanation

1. Schedule Trigger

Extracted fields include:

• Employee reference
• Status
• Billable, non-billable, absence hours
• Total hours
• Reporting period

Processing Path A — Submitted Timesheets

3. Filter Submitted

Filters timesheets where dbt__Status__c == "Submitted".

Each employee’s timesheet is processed individually.

5. Retrieve Line Items

Fetches all dbt__Timesheet_Line_Item__c entries:

• Project / Client
• Activity
• Duration
• Work description
• Billable category

6. Convert Line Items to HTML (Code Node)

Transforms line items into well-structured HTML tables for clean LLM input.

7. OpenAI — Weekly Activity Summary

OpenAI receives the HTML + Employee ID and returns a 4-point activity summary avoiding:

• Hours
• Dates
• Repeated or irrelevant metadata

8. Fetch Employee Details

Retrieves employee name, email, and additional fields if needed.

9. Merge Employee + Summary

Combines:

• Timesheet data
• Employee details
• OpenAI summary

Creates a unified object.

10. Prepare Submitted Section (Code Node)

Produces the formatted block used in the final email:

Employee: Name  
Period: Start → End  
Status: Submitted  
Total Hours: ...
