My offshore personnel rota lives in Excel and has grown into several separate tabs. I need a VBA-driven solution that will: 1. Instantly flag any date clash whenever the same person is scheduled on overlapping days across different tabs. 2. Check each assignment against the rest-period rule: if someone has spent less than one-third of their previous offshore trip at home, the sheet should warn that they are unavailable. The system must react in two ways—show a pop-up alert the moment the clash or rest-period issue is created or edited, and visually highlight the affected cells so the problem is easy to spot later. Key points while you build: • The checks have to be fully automatic; no manual button pressing. • All tabs currently follow the same column layout for name, start date and end date—keep that structure intact. • The file will be shared among supervisors with different security settings, so please avoid anything that requires external add-ins. Deliverables I expect: • A single, unlocked Excel workbook containing the working VBA code. • Clear comments inside the code so I can tweak rules in future. • A brief read-me sheet explaining where to paste new tabs or rename existing ones without breaking the automation. Once everything runs smoothly on my side—clashes caught, rest rules enforced, alerts and highlighting consistent—the project is complete.

I can build this automated rota clash and rest-period validator using a dynamic Workbook_SheetChange event, ensuring instant alerts and highlighting without any manual button clicks. To enforce the 1/3 rest rule, the VBA will scan and chronologically sequence each person's historic trips across all tabs, calculate their previous home-stay gap, and instantly trigger a warning if it falls short. Since your sheets share a uniform layout, the solution will be entirely modular, meaning supervisors can add or rename tabs easily without breaking the script. To ensure the 1/3 rest-period check is flawless, how should the macro handle situations where a person's previous offshore trip is split or logged across two different tabs, or is each trip always fully contained within a single tab?

Hi, You’ve got a rota problem that’s easy to miss in Excel until it becomes a scheduling conflict, and I can see exactly where the hidden pain is: cross-tab clashes and rest-rule breaches that need to surface instantly, not after a supervisor notices them later. I’ve built VBA-driven workbook automation for multi-tab business files before, and I can set this up so edits are checked automatically, overlapping assignments are flagged immediately, and the affected cells are highlighted for quick review. I’ll keep your current layout intact, avoid external add-ins, and add clear code comments plus a brief read-me sheet so future tab changes remain safe and simple. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can start by mapping the tab structure and the name/start/end-date columns, then wire in the clash detection and rest-period logic so it reacts on change without manual buttons. Should the rest-period warning use calendar days off between trips, or only full home days excluding travel days? Best regards, Asad Looking forward to your reply so we can finalize the exact plan.

You’re looking for fully automatic VBA that safeguards an Excel-based offshore rota with multiple tabs sharing the same layout (Name, Start Date, End Date). I’ll build event-driven checks that run immediately on any create/edit so supervisors see issues right away: (1) overlapping-date clashes for the same person across tabs, and (2) rest-period compliance, warning when the previous offshore trip’s time at home is less than one-third. Implementation approach: - Hook into Worksheet_Change/Calculate events so no button pressing is required. - Read assignments from all tabs into an in-memory map keyed by person, then compare ranges to flag overlaps. - Determine previous offshore trips per person and compute home-rest time; highlight cells and raise a clear pop-up for both rules. - Visually mark affected name/date cells with consistent formatting. Deliverables: - Single unlocked Excel workbook with commented VBA for future rule tweaks. - Read-me sheet explaining where to paste new tabs or how to rename without breaking automation. I’ll keep it self-contained (no external add-ins), so it works across differing security settings.

Multiple tabs growing separately is exactly where clash detection breaks down. I would write a VBA macro that scans all tabs, flags personnel conflicts, and outputs a clean summary in one place. Done in 2 to 3 days. Can start today. The bid reflects what is in the description. Final scope depends on tab count and what the output needs to show. Want to jump on a quick call?

Hi, there! I have strong experience building VBA driven Excel scheduling and workforce control tools. I can create automatic cross sheet clash detection, rest period validation, instant pop up warnings, and cell highlighting without changing your current tab structure or using external add ins. I have completed similar rota and compliance workbooks with worksheet event triggers, date overlap checks, configurable rules, and clear code comments. I will deliver an unlocked workbook with a read me sheet and test all scenarios before handover. 1. Should the one third rest period be calculated from the total length of the employee’s immediately previous offshore trip? 2. Should warnings block the entry completely or allow supervisors to save it after acknowledgment? Best regards, George

I’ve built VBA rota systems for offshore crews with multi-tab conflict checks before, so this is routine. I’ll embed Worksheet_Change event handlers in each rota tab to scan name, start and end date columns, cross-reference against all other tabs via a central name-indexed dictionary, and flag overlaps or rest-period breaches instantly with pop-ups and cell color. The workbook stays unlocked, uses no add-ins, and all logic lives in one module under the same column headers you already have. Comments will mark rule thresholds so you can adjust fractions or thresholds later. Thanks, Andrii
