Summary A US-based oil & gas cybersecurity firm implemented a mobile-first Canvas App integrated with Dynamics 365 Project Operations to unify time, expense, and material submission, tracking, and approval. The solution enabled project-specific approval workflows where only assigned approvers could validate submitted records. CloudFronts introduced a dual-mode interface (Day Mode and Week Mode) to improve usability for both field engineers and managers. Submission and approval cycle time reduced from hours/days to near real-time visibility. Table of Contents 1. Customer Scenario 2. Solution Overview 3. Key UX Features 4. Functional Implementation 5.

Conclusion Customer Scenario A Texas-based cybersecurity firm specializing in operational technology (OT) security for oil rigs manages multiple concurrent field projects using Dynamics 365 Project Operations. Employees and resources were responsible for logging: Time entries Expense entries (travel, accommodation, airfare, etc.) Material usage logs (equipment, parts, consumables, etc.) However, the system was not designed for mobile-first usage, and processes were fragmented across multiple interfaces. Key Challenges Field engineers & other Resources could not efficiently submit entries from mobile devices Time, expense, and material tracking existed in separate workflows Approval processes had to be restricted to project-specific stakeholders Project managers lacked real-time visibility into resource usage • Delays in submission can cause downstream billing and reporting issues Project tracking accuracy can get compromised, and reporting delays directly affected client communication and billing cycles. Solution Overview CloudFronts designed and deployed a unified mobile application using Power Apps (Canvas Apps) integrated with Dynamics 365 Project Operations. Objective: One app → All submissions → Controlled approvals → Real-time visibility What the App Enables For Field Users: Submit time entries (daily or weekly) Create expense entries with receipt validation Log material consumption against projects Track submission status instantly For Project Approvers: View only entries related to assigned projects Approve or reject submissions directly from mobile Maintain audit-ready approval workflows Key UX Features The application is designed with a strong focus on usability for both resources and project approvers, ensuring a seamless mobile experience across submission and approval workflows. 1. Day Mode / Week Mode Toggle The app provides a flexible entry experience through a dual-mode interface: Day Mode: Enables detailed entry for a single day, ideal for precise logging and corrections. Week Mode: Allows bulk entry across multiple days, reducing effort for repetitive data entry. This flexibility significantly improves usability across different working styles and scenarios. 2. Calendar-Based Swipe Navigation The application introduces a Dynamics-style calendar navigation with swipe support, allowing users to: Traverse across multiple days or weeks effortlessly View and manage multiple submission records in sequence Navigate between historical and current entries with minimal effort This mobile-first interaction design reduces friction in high-frequency data entry scenarios. 3. Unified Submission & Approval Experience The UI/UX is intentionally designed to mirror the complete lifecycle of a record, ensuring consistency between submission and approval stages. Each record follows a structured lifecycle aligned with Dynamics 365 stages: Submitted Pending Approved Rejected Recall Requested Recall Request Approved Recall Request Rejected The interface dynamically adapts based on the current stage: Action buttons (Approve, Reject, Recall, etc.) are conditionally visible Status indicators are clearly displayed Users experience the same structured flow from creation to closure This ensures clarity, reduces errors, and improves user confidence in the system. 4. Dynamic Action-Based UI (Smart Button Behavior) The app intelligently modifies UI controls based on record state: Submit button appears only for draft entries Approve/Reject buttons are visible only to project approvers Recall option is available only after submission Post-approval states restrict further edits This enforces role-based and state-based control, preventing invalid actions and maintaining process integrity. 5. Conditional Receipt Upload for Expense Entries Expense submission logic is enhanced with category-driven validation: Mandatory: Airline tickets, OT hardware purchases Optional: Meals, local travel This balances compliance requirements with user convenience, avoiding unnecessary friction. 6. On-Demand Data Refresh Users can manually refresh data within the app to: Fetch the latest submission and approval statuses Sync newly created or updated records Ensure real-time visibility without relying solely on background refresh Especially useful in environments with intermittent connectivity. 7. Mobile-First Interaction Design Touch-friendly controls Swipe navigation Lightweight screens for faster performance Minimal navigation depth This ensures field engineers working in remote or on-site environments can operate efficiently. Functional Implementation This section outlines how the solution was implemented within Dynamics 365 Project Operations and the Power Platform to enable end-to-end submission and approval management. 1. Unified Data Model in Dataverse All three entry types — Time, Expense, and Material — are structured within Dataverse and linked to: Project Resource (User) Approval records Supporting documents (for expenses) Each submission creates a corresponding record with a defined lifecycle stage, ensuring consistency across all entry types. 2. Submission Logic from Canvas App Each submission type follows a structured flow: User selects project and entry type (Time / Expense / Material) Required fields are validated based on entry type Conditional logic enforces: Receipt requirement (for specific expense categories) Mandatory fields (based on business rules) Record is created in Dataverse Submission triggers backend approval workflow This ensures that all records entering the system are complete, validated, and ready for approval processing. 3. Approval Record Creation & Routing Upon submission: A corresponding approval record is automatically created The system identifies project-specific approvers Key behavior: Only assigned project approvers can view and act on records Approval actions update the main record status 4. Record Lifecycle Management (Status-Driven System) Lifecycle: Draft → Submitted → Pending → Approved / Rejected → Recall Flow Users submit records → moves to Submitted Approvers review → Approved or Rejected Users request recall → Recall Requested Approvers respond → Recall Approved or Rejected Controlled through: Power Apps UI logic MS Bound Actions for submission and approval handling Dataverse status fields 5. Expense Receipt Handling (Integrated from Previous Solution) Receipt upload enforced conditionally Files stored as Notes (Annotations) in Dataverse Linked to expense records This eliminates manual document handling and ensures compliance.
