+
+This template can be used when responding to issues related to export timeouts when exporting DLP Impact Analysis data.

+
+## Template: DLP Impact Analysis Export Timeout
+
+**Use when:** Users report that they cannot export DLP Impact Analysis results due to timeouts or large dataset sizes
+
+**Response:**
+
+Thank you for reporting this issue with exporting DLP Impact Analysis data!
+
+### Issue Summary
+
+This is a **known limitation** when analyzing DLP policies with broad scope (such as "Strict" policies that block many connectors). The large number of impacted apps and flows creates too many records to export through the standard Canvas app or model-driven app export functions.
+
+### Root Cause
+
+The export timeouts are caused by platform limitations:
+- **Canvas Apps**: 2,000 record delegation limit
+- **Dataverse Excel Export**: 50,000 row limit  
+- **Browser Timeouts**: 30-120 seconds (varies by browser)
+- **API Throttling**: Service protection limits for large queries
+
+When your DLP policy analysis generates more records than these limits, exports will timeout or fail.
+
+### Solutions Available
+
+We've created comprehensive troubleshooting documentation with **5 different solutions** to handle large DLP Impact Analysis exports:
+
+🔗 **[DLP Impact Analysis Export Timeout Troubleshooting Guide](../docs/troubleshooting/dlp-impact-analysis-export-timeout.md)**
+
+#### Quick Reference - Choose Your Approach:
+
+| Your Scenario | Recommended Solution | Complexity |
+|--------------|---------------------|------------|
+| < 2,000 records | Filter in Canvas App and export | ✅ Low |
+| 2,000 - 50,000 records | Use filtered views in model-driven app | ✅ Low |
+| > 50,000 records | **Power Automate batch export** | ⚠️ Medium |
+| Technical users | PowerShell with FetchXML pagination | 🔧 High |
+| Analysis only (no export needed) | Power BI integration | ✅ Low-Medium |
+
+### Recommended Solution: Power Automate Flow Export
+
+For most users with large datasets, we recommend **Solution 1** from the troubleshooting guide:
+
+**Create a Power Automate flow** that:
+1. Retrieves data in batches of 5,000 records
+2. Exports to SharePoint/OneDrive or sends via email
+3. Handles any dataset size without timeouts
+4. Runs automatically in the background
+
+👉 [Step-by-step instructions for Power Automate export](../docs/troubleshooting/dlp-impact-analysis-export-timeout.md#solution-1-power-automate-flow-export-recommended-for-large-datasets)
+
+### For Technical Users: PowerShell Script
+
+We've also created a **ready-to-use PowerShell script** that automates the export:
+
+📥 **[Export-DLPImpactAnalysis.ps1](../docs/scripts/Export-DLPImpactAnalysis.ps1)**
+
+```powershell
+# Install the required module
+Install-Module Microsoft.Xrm.Data.PowerShell -Scope CurrentUser
+
+# Run the export
+.\Export-DLPImpactAnalysis.ps1 -EnvironmentUrl "https://yourorg.crm.dynamics.com"
+```
+
+The script handles pagination automatically and exports to CSV.
+
+### Quick Workaround: Export Filtered Subsets
+
+If you need data immediately:
+
+1. Open the **Impact Analysis** app
+2. Apply filters to reduce dataset size:
+   - Filter by **Environment** 
+   - Filter by **Decision Status** (e.g., "Needs Review")
+   - Filter by **Date Range** (last 30 days)
+3. Export the filtered subset (should be < 2,000 records)
+4. Repeat for other filters to get complete dataset in parts
+
+### Next Steps
+
+1. Review the [complete troubleshooting guide](../docs/troubleshooting/dlp-impact-analysis-export-timeout.md)
+2. Choose the solution that fits your scenario and technical skills
+3. If you continue experiencing issues after trying these solutions, please provide:
+   - Approximate number of records in your DLP Impact Analysis
+   - Which solution you tried
+   - Any error messages or screenshots
+   - Your CoE Starter Kit version

+
+### Prevention: Managing Large Datasets
+
+To prevent this issue in the future:
+
+✅ **Run targeted analyses**: Analyze by environment rather than tenant-wide  
+✅ **Clean up old data**: Delete completed analyses after 90 days  
+✅ **Use Power BI**: Analyze directly without exporting

+## Notes for Maintainers
+
+- This issue typically occurs with "Strict" DLP policies that affect 10,000+ apps/flows
+- The most common successful solution is Power Automate flow export (Solution 1)
+- Technical users prefer the PowerShell script
+- Some users may need guidance on how to estimate their record count first
+- Consider adding telemetry to track how many records are in typical analyses
+- Future enhancement: Add built-in batch export functionality to the Impact Analysis app
