 ### Common Questions
 
+**Q: Why are my sync flows taking 7+ hours to complete?**
+
+A: This is typically caused by API throttling when multiple flows run concurrently. To resolve:
+1. Set `admin_DelayObjectInventory` to `Yes`
+2. Verify `admin_DelayInventory` is set to `Yes`
+3. Ensure `admin_FullInventory` is set to `No` (for regular runs)
+
+The delay settings spread API calls over time, preventing throttling and reducing runtime to 30-120 minutes. See the **[Flow Performance Troubleshooting Guide](./TROUBLESHOOTING-FLOW-PERFORMANCE.md)** for detailed resolution steps.
+
 **Q: Why aren't all my resources showing up in the inventory?**
 
 A: The inventory flows run in incremental mode by default, which only syncs new or recently modified resources. To capture all resources, you need to run a full inventory by setting the `admin_FullInventory` environment variable to `Yes`. Remember to set it back to `No` after the full inventory completes.

+# Troubleshooting: Sync Flow Performance and Long Runtimes
+
+This guide helps resolve issues where inventory sync flows (particularly **Admin | Sync Template v3 (Flow Action Details)** and **Admin | Sync Template v4 (Flows)**) run for extended periods (7+ hours) instead of completing within expected timeframes (30 minutes to 2 hours).

+
+---
+
+## Quick Fix
+
+If your sync flows are taking 7+ hours to complete:
+
+1. Navigate to **Power Apps** → **Solutions** → **Center of Excellence - Core Components** → **Environment Variables**
+2. Find `admin_DelayObjectInventory` and set **Current Value** = `Yes`
+3. Find `admin_DelayInventory` and verify **Current Value** = `Yes` (should already be Yes)
+4. Find `admin_FullInventory` and verify **Current Value** = `No` (for regular scheduled runs)
+5. Wait for the next **Admin | Sync Template v4 (Driver)** run to apply the changes
+
+✅ **Expected Result**: Flow completion times will return to 30-90 minutes for v4 Flows and 1-2 hours for v3 Flow Action Details.
+
+---
+
+## Issue Description
+
+### Symptoms
+- **Admin | Sync Template v3 (Flow Action Details)** runs for 7+ hours
+- **Admin | Sync Template v4 (Flows)** runs for extended periods
+- Multiple sync flows triggered simultaneously on environment table changes
+- Flow runs show many retries or long wait times between actions
+
+### Affected Flows
+- Admin | Sync Template v3 (Flow Action Details)
+- Admin | Sync Template v4 (Flows)
+- Admin | Sync Template v4 (Apps)
+- Admin | Sync Template v4 (Cloud Flows)
+- Other inventory sync flows triggered by environment updates
+
+### When This Occurs
+This issue typically manifests when:
+- Multiple environments are being inventoried simultaneously
+- The Driver flow updates many environment records at once
+- Delay settings are disabled (`admin_DelayObjectInventory = No`)
+- Running in full inventory mode (`admin_FullInventory = Yes`) without delays
+
+---
+
+## Root Cause
+
+### The Throttling Cascade
+
+When the **Admin | Sync Template v4 (Driver)** flow updates environment records in the CoE Dataverse environment, it triggers 20+ child flows simultaneously (one for each environment). Without delay settings enabled, this creates a **cascade of concurrent API calls**:
+
+1. **Driver flow** updates 20+ environment records
+2. Each update triggers **multiple child flows** (Apps, Flows, Connectors, etc.)
+3. Each child flow makes **hundreds to thousands** of Dataverse API calls
+4. Total concurrent calls can reach **50,000+ per minute**
+
+### Dataverse Throttling Limits
+
+Microsoft Dataverse enforces service protection limits:
+- **6,000 API requests per 5 minutes** per user
+- **52,429 API requests per 5 minutes** per tenant (depending on licenses)
+- **20 concurrent requests** per user
+
+**Reference**: [Dataverse Service Protection Limits](https://learn.microsoft.com/en-us/power-apps/developer/data-platform/api-limits)
+
+### What Happens When Limits Are Exceeded
+
+When flows exceed these limits:
+1. Dataverse returns **429 (TooManyRequests)** errors
+2. Power Automate automatically **retries with exponential backoff**
+3. Initial retry: Wait 1 minute
+4. Subsequent retries: Wait 2 min → 4 min → 8 min → 16 min → 32 min...
+5. Total retry time can extend flows from **minutes to hours**
+
+### Why Delays Fix This
+
+The `admin_DelayObjectInventory` variable adds a **randomized delay** (1-5 minutes) before each environment's inventory starts. This:
+- ✅ Spreads API calls over time instead of all at once
+- ✅ Keeps request rate under throttling limits
+- ✅ Eliminates retry cascades
+- ✅ Reduces total runtime despite adding delays
+
+**Paradox**: Adding delays makes flows complete **faster** by avoiding throttling.
+
+---
+
+## Detailed Resolution Steps
+
+### Step 1: Verify Current Settings
+
+1. Open **Power Apps** → Your CoE Environment
+2. Navigate to **Solutions** → **Center of Excellence - Core Components**
+3. Click **Environment Variables**
+4. Check the current values of these three variables:
+
+| Variable Name | Current Value Should Be | Description |
+|--------------|------------------------|-------------|
+| `admin_DelayObjectInventory` | **Yes** | Adds delay for object inventory (apps, flows, etc.) |
+| `admin_DelayInventory` | **Yes** | Adds delay for environment-level inventory |
+| `admin_FullInventory` | **No** | Only "Yes" when running initial inventory or troubleshooting |
+
+### Step 2: Update Delay Settings
+
+If `admin_DelayObjectInventory` is set to `No`:
+
+1. Click on **admin_DelayObjectInventory**
+2. In the **Current Value** field, enter: `Yes`
+3. Click **Save**
+
+If `admin_DelayInventory` is set to `No` (should already be Yes by default):
+
+1. Click on **admin_DelayInventory**
+2. In the **Current Value** field, enter: `Yes`
+3. Click **Save**
+
+### Step 3: Verify Full Inventory Is Disabled
+
+Unless you're running an initial inventory or troubleshooting:
+
+1. Click on **admin_FullInventory**
+2. Verify **Current Value** = `No`
+3. If it's set to `Yes`, change it to `No` and click **Save**
+
+⚠️ **Important**: Running full inventory with delays disabled causes the longest runtimes. Always enable delays when running full inventory.
+
+### Step 4: Wait for Next Driver Run
+
+The delay settings are read when flows are triggered. They will take effect:
+- On the next **Admin | Sync Template v4 (Driver)** scheduled run
+- OR when you manually trigger the Driver flow
+- OR when environment records are updated
+
+You do **NOT** need to:
+- ❌ Turn flows off and back on
+- ❌ Restart Power Automate
+- ❌ Re-import solutions
+
+### Step 5: Monitor Flow Performance
+
+After the settings are applied:
+
+1. Go to **Power Automate** → **Cloud flows**
+2. Find **Admin | Sync Template v3 (Flow Action Details)**
+3. Click on the flow and view **Run history**
+4. Check the most recent run:
+   - ✅ **Expected**: Completes in 1-2 hours
+   - ❌ **Still slow**: Continue to Advanced Troubleshooting
+

+
+## Understanding the Environment Variables
+
+### admin_DelayObjectInventory
+
+**Purpose**: Prevents API throttling for object-level inventory (apps, flows, connectors, etc.)
+
+**How it works**:
+- When `Yes`: Adds a random delay (1-5 minutes) before processing each environment
+- When `No`: Processes all environments simultaneously
+
+**Default Value** (as of v4.51+): `Yes`  
+**Recommendation**: Keep set to `Yes` for all tenants
+
+**When to use `No`**:
+- ⚠️ Small tenants with <5 environments (testing/demo)
+- ⚠️ Debugging specific flow issues
+- ⚠️ Only when you understand the throttling risk
+
+### admin_DelayInventory
+
+**Purpose**: Adds general delays for Dataverse health
+
+**How it works**:
+- When `Yes`: Implements delay logic in main inventory flows
+- When `No`: No delays (only for debugging)
+
+**Default Value**: `Yes`  
+**Recommendation**: **Always keep set to `Yes`**
+
+**When to use `No`**:
+- ⚠️ Never recommended for production
+- Only for debugging in isolated test environments
+
+### admin_FullInventory
+
+**Purpose**: Controls incremental vs. full inventory mode
+
+**How it works**:
+- When `No`: Only syncs new or recently modified resources (incremental)
+- When `Yes`: Syncs ALL resources in ALL environments (full inventory)
+
+**Default Value**: `No`  
+**Recommendation**: Keep set to `No` for regular scheduled runs
+
+**When to use `Yes`**:
+- ✅ Initial CoE setup (first-time inventory)
+- ✅ Troubleshooting missing resources
+- ✅ After major tenant changes
+- ⚠️ **MUST** have both delay variables set to `Yes` when using full inventory
+
+**After full inventory completes**: Set back to `No`
+
+---
+
+## Expected Runtime After Fix
+
+With delay settings properly configured:
+
+### Incremental Mode (admin_FullInventory = No)
+
+| Flow | Environment Count | Expected Runtime |
+|------|------------------|------------------|
+| Admin \| Sync Template v4 (Flows) | 1-10 envs | 15-45 minutes |
+| Admin \| Sync Template v4 (Flows) | 10-50 envs | 30-90 minutes |
+| Admin \| Sync Template v4 (Flows) | 50+ envs | 1-2 hours |
+| Admin \| Sync Template v3 (Flow Action Details) | 1-10 envs | 30-60 minutes |
+| Admin \| Sync Template v3 (Flow Action Details) | 10-50 envs | 1-2 hours |
+| Admin \| Sync Template v3 (Flow Action Details) | 50+ envs | 2-3 hours |
+
+### Full Inventory Mode (admin_FullInventory = Yes)
+
+| Tenant Size | Expected Runtime |
+|-------------|------------------|
+| Small (<100 apps/flows) | 2-4 hours |
+| Medium (100-1000 apps/flows) | 4-8 hours |
+| Large (1000+ apps/flows) | 8-12 hours |
+| Enterprise (10,000+ apps/flows) | 12-24+ hours |
+
+⚠️ **Full inventory mode is resource-intensive**. Plan accordingly and run during off-peak hours.
+
+---
+
+## Advanced Troubleshooting
+
+If flows are still slow after enabling delays:
+
+### Check License Allocation
+
+Insufficient Power Apps licenses reduce API limits:
+
+1. Verify the service account has **Power Apps Per User** or **Power Apps Premium**
+2. Check tenant-level API capacity in **Power Platform Admin Center**
+3. Review if you need to purchase additional capacity
+
+**Test your license allocation**:
+```
+Power Automate > Monitor > API Limits
+```
+
+Look for **429 errors** or **throttling warnings** in flow runs.
+
+### Verify Connector Permissions
+
+The service account must have:
+- ✅ System Administrator role in CoE environment
+- ✅ Power Platform Admin role in Microsoft Entra ID
+- ✅ Permissions to call Microsoft Dataverse connector
+- ✅ Permissions to call HTTP with Azure AD connector
+
+### Check for Concurrent Manual Triggers
+
+If someone is manually triggering flows while scheduled runs are happening:
+- Pause manual troubleshooting during scheduled inventory
+- Schedule Driver flow for off-peak hours (e.g., 2 AM local time)
+
+### Review Flow Run History for Specific Errors
+
+1. Go to the slow-running flow
+2. Click on a recent run
+3. Expand each action and look for:
+   - **429 errors** → Throttling (enable delays)
+   - **401/403 errors** → Permissions issue
+   - **500 errors** → Dataverse service issue
+   - **Timeout errors** → Network or performance issue
+
+### Increase Lookback Window (If Using Incremental Mode)
+
+If you're missing recent changes:
+
+1. Find `admin_InventoryFilter_DaysToLookBack`
+2. Increase from default `7` to `14` or `30`
+3. This increases runtime but ensures better coverage
+
+### Consider Splitting Inventory by Environment Groups
+
+For very large tenants (100+ environments):
+- Use environment filters to split inventory into batches
+- Run different batches at different times
+- This is an advanced configuration not covered in this guide
+
+---
+
+## Prevention
+
+### For New Installations
+
+✅ **Default settings (v4.51+) already prevent this issue**  
+✅ `admin_DelayObjectInventory` defaults to `Yes`  
+✅ `admin_DelayInventory` defaults to `Yes`  
+
+No action needed if installing fresh.
+
+### For Existing Installations
+
+If you're upgrading from older versions:
+
+1. ✅ Review environment variables after each upgrade
+2. ✅ Verify delay settings are enabled
+3. ✅ Test flow performance after upgrade
+4. ✅ Read upgrade release notes for environment variable changes
+
+### Best Practices
+
+1. **Monitor regularly**: Check flow run times weekly
+2. **Set alerts**: Configure failure alerts for critical flows
+3. **Off-peak scheduling**: Run Driver flow during low-usage hours
+4. **Incremental by default**: Only use full inventory when necessary
+5. **Document settings**: Keep a record of your environment variable configurations
+
+### When to Re-enable Delays After Debugging
+
+If you temporarily disabled delays for troubleshooting:
+- ✅ Re-enable immediately after debugging session
+- ✅ Don't leave delays disabled overnight
+- ✅ Set a reminder to restore production settings
+
+---
+
+## Summary
+
+### The Problem
+Concurrent flow executions exceed Dataverse API limits, causing throttling and exponential retry backoff that extends runtimes from minutes to hours.
+
+### The Solution
+Enable delay environment variables to spread API calls over time:
+- `admin_DelayObjectInventory = Yes`
+- `admin_DelayInventory = Yes`
+
+### The Result
+- ✅ Flows complete in 30 minutes to 2 hours instead of 7+ hours
+- ✅ No throttling errors
+- ✅ Predictable, consistent performance
+- ✅ Better tenant health
+
+### Key Takeaway
+**Adding delays makes flows faster** by preventing throttling retries.

+## Template: Sync Flows Taking 7+ Hours to Complete
+
+**Use when:** Users report that inventory sync flows (v3 Flow Action Details, v4 Flows, etc.) are running for extended periods (7+ hours) instead of completing within expected timeframes
+
+**Response:**
+
+Thank you for reporting this issue! The extended runtime (7+ hours) is caused by **API throttling from concurrent flow executions**, not a bug in the flows themselves.
+
+### 🎯 Immediate Solution
+
+1. **Enable throttling prevention settings**:
+   - Navigate to **Power Apps** → **Solutions** → **Center of Excellence - Core Components** → **Environment Variables**
+   - Find `admin_DelayObjectInventory` and set **Current Value** = `Yes`
+   - Find `admin_DelayInventory` and verify **Current Value** = `Yes` (should already be Yes)
+
+2. **Verify inventory mode**:
+   - Find `admin_FullInventory` and verify **Current Value** = `No` (for regular scheduled runs)
+
+3. **Allow settings to take effect**:
+   - Changes apply on the next **Admin | Sync Template v4 (Driver)** run
+   - No need to restart flows or Power Automate
+
+### 📊 Expected Results
+
+With delays enabled and incremental mode:
+- **v4 Flows**: 30-90 minutes (depending on tenant size)
+- **v3 Flow Action Details**: 1-2 hours (processes more detailed data)
+
+### 🔍 Why This Happens
+
+When the Driver flow updates environment records, it triggers 20+ child flows simultaneously. Without delay settings, this creates thousands of concurrent API calls that exceed Dataverse throttling limits (6,000 requests per 5 minutes). The flows then retry with exponential backoff, extending runtime from minutes to hours.
+
+**Paradox**: Adding delays actually makes flows **complete faster** by preventing throttling retries.
+
+### 📖 Detailed Troubleshooting Guide
+
+For comprehensive information including:
+- Root cause analysis
+- Advanced troubleshooting steps
+- Expected runtimes by tenant size
+- Prevention best practices
+
+See the **[Flow Performance Troubleshooting Guide](../CenterofExcellenceCoreComponents/TROUBLESHOOTING-FLOW-PERFORMANCE.md)**
+
+### ✅ Default Settings Updated
+
+**Good news**: Starting with version 4.51+, `admin_DelayObjectInventory` defaults to `Yes` to prevent this issue in new installations. If you're on an older version or the setting was changed, you'll need to update it manually.
+
+### 🔄 If Still Experiencing Issues
+
+If flows are still slow after enabling delays:
+1. Verify the service account has **Power Apps Per User** or **Power Apps Premium** license
+2. Check for **429 (TooManyRequests)** errors in flow run history
+3. Review API limits in **Power Automate** → **Monitor** → **API Limits**
+4. See the troubleshooting guide for advanced scenarios
+
+Let us know if the performance improves after enabling the delay settings!
