    @{Value=3; Label="Completed"; Color="#107C10"},
    @{Value=4; Label="Cancelled"; Color="#D13438"}
)

# Note: Use Power Apps UI for easier column creation
# Below is conceptual API approach

# Create lookup column (Project Manager)
$lookupAttribute = @{
    SchemaName = "con_ProjectManager"
    DisplayName = "Project Manager"
    Description = "User responsible for project"
    RequiredLevel = "ApplicationRequired"
    Type = "Lookup"

Step 2: Configure Table Relationships

Create 1:N Relationships

# Conceptual relationship definitions

# Project → Task (1:N)
$projectTaskRelationship = @{
    SchemaName = "con_project_task"
    ReferencedEntity = "con_project"
    ReferencedAttribute = "con_projectid"
    ReferencingEntity = "con_task"
    ReferencingAttribute = "con_projectid"
    RelationshipBehavior = "Parental"  # Cascade delete
    CascadeConfiguration = @{
        Assign = "Cascade"
        Delete = "Cascade"
        Merge = "Cascade"
        Reparent = "Cascade"
        Share = "Cascade"
        Unshare = "Cascade"
    }
}

# Task → Time Entry (1:N)
$taskTimeEntryRelationship = @{
    SchemaName = "con_task_timeentry"
    ReferencedEntity = "con_task"
    ReferencingEntity = "con_timeentry"
    RelationshipBehavior = "Parental"
}

# Project → Resource Allocation (1:N)
$projectResourceRelationship = @{
    SchemaName = "con_project_resourceallocation"
    ReferencedEntity = "con_project"
    ReferencingEntity = "con_resourceallocation"
    RelationshipBehavior = "Referential"  # Don't cascade delete
}

var ProjectForm = ProjectForm || {};

ProjectForm.OnLoad = function(executionContext) {
    var formContext = executionContext.getFormContext();
    
    // Calculate and display project duration
    ProjectForm.calculateDuration(formContext);
    
    // Load team members count
    ProjectForm.loadTeamStats(formContext);
    
    // Set up event handlers
    formContext.getAttribute("con_startdate").addOnChange(ProjectForm.calculateDuration);
    formContext.getAttribute("con_enddate").addOnChange(ProjectForm.calculateDuration);
};

ProjectForm.calculateDuration = function(executionContext) {
    var formContext = executionContext.getFormContext();
    
    var startDate = formContext.getAttribute("con_startdate").getValue();
    var endDate = formContext.getAttribute("con_enddate").getValue();
    
    if (startDate && endDate) {
        var duration = Math.floor((endDate - startDate) / (1000 * 60 * 60 * 24));
        
        // Display duration (requires custom field: con_duration)
        formContext.getAttribute("con_duration").setValue(duration);
        
        // Update notification
        formContext.ui.setFormNotification(
            "Project duration: " + duration + " days",
            "INFO",
            "duration"
        );
    }
};

ProjectForm.loadTeamStats = function(formContext) {
    var projectId = formContext.data.entity.getId().replace(/[{}]/g, "");
    
    // Query related resource allocations
    var fetchXml = [
        "<fetch aggregate='true'>",
        "  <entity name='con_resourceallocation'>",
        "    <attribute name='con_resourceallocationid' aggregate='count' alias='count'/>",
        "    <filter>",
        "      <condition attribute='con_projectid' operator='eq' value='" + projectId + "'/>",
        "    </filter>",
        "  </entity>",
        "</fetch>"
    ].join("");
    
    Xrm.WebApi.retrieveMultipleRecords(
        "con_resourceallocation",
        "?fetchXml=" + encodeURIComponent(fetchXml)
    ).then(
        function success(result) {
            if (result.entities.length > 0) {
                var count = result.entities[0].count;
                formContext.ui.setFormNotification(
                    "Team Members: " + count,
                    "INFO",
                    "teamcount"
                );
            }
        },
        function error(error) {
            console.error("Error loading team stats:", error.message);
        }
    );
};

ProjectForm.OnSave = function(executionContext) {
    var formContext = executionContext.getFormContext();
    
    // Validate budget before saving
    var budget = formContext.getAttribute("con_budget").getValue();
    var actualCost = formContext.getAttribute("con_actualcost").getValue();
    
    if (actualCost > budget * 1.2) {
        executionContext.getEventArgs().preventDefault();
        Xrm.Navigation.openAlertDialog({
            text: "Project is significantly over budget. Please review before saving.",
            confirmButtonLabel: "OK"

          Days Overdue: [Calculated]

Real-World Enterprise Example

Scenario: Contoso Consulting Firm

Challenge: Managing 50+ concurrent client projects with 200+ employees

• No centralized project tracking
• Time entry done in spreadsheets
• Resource allocation conflicts
• Budget overruns not caught early
• Client reporting manual and time-consuming

Solution Implementation:

1. Dataverse Schema:

   • 5 custom tables (Project, Task, Time Entry, Resource, Client)
   • 20+ custom fields with business logic
   • Automated rollups for financial tracking

2. Model-Driven App:

   • 4 custom forms with JavaScript validation
   • 12 views for different stakeholder needs
   • 6 dashboards (Executive, PM, Team Member)
   • Business Process Flow for standardized project lifecycle

3. Integration:

   • Power BI for executive reporting
   • Power Automate for 15+ workflows
   • Outlook integration for time entry
   • Teams integration for collaboration

Results After 6 Months:

Metric	Before	After	Improvement
Time to create project	2 hours	15 minutes	87% faster
Budget overruns	25% of projects	8% of projects	68% reduction
Resource utilization	65%	85%	31% increase
Time entry compliance	60%	95%	58% increase
Client reporting time	4 hours/project	30 minutes	87% faster
PM productivity	Baseline	+40%	Significant gain

Best Practices Summary

DO:

1. ✅ Design schema before building UI
2. ✅ Use business rules for simple logic (no code)
3. ✅ Implement rollup fields for aggregations
4. ✅ Create separate security roles for each persona
5. ✅ Use Business Process Flows for standardization
6. ✅ Enable auditing for compliance requirements
7. ✅ Use solutions for ALM (export/import)
8. ✅ Test in dev environment before production
9. ✅ Document customizations for maintenance
10. ✅ Use FetchXML for complex queries

DON'T:

1. ❌ Over-customize with JavaScript (use platform features first)
2. ❌ Create too many tables (normalize appropriately)
3. ❌ Skip relationship configuration
4. ❌ Grant excessive permissions
5. ❌ Forget to publish customizations
6. ❌ Ignore performance (limit form fields < 100)
7. ❌ Hard-code GUIDs in JavaScript
8. ❌ Skip field-level security for sensitive data
9. ❌ Create forms without business rules
10. ❌ Deploy without backup/rollback plan
