FAQ

Which Odoo versions / editions are supported?

This module targets Odoo 19 and works with both Community and Enterprise editions, including Odoo.sh and on-premise deployments.

Do I need Odoo Enterprise Gantt?

No. NexGen Gantt is a standalone interactive Gantt suite built on standard Odoo Web. It does not require Enterprise Gantt.

Who publishes and supports this app?

NexGen Solutions publishes the suite. Support email: nexgensolutionsodoo@gmail.com.

Does Gantt invent workflow states like Confirm / Done / Approve?

No. NexGen Gantt is safety-first: adapters write schedule/planning fields only. Native Odoo forms and buttons remain the source of truth for workflow.

Are writes protected by ACLs and record rules?

Yes. Timeline reads and writes use the current user’s access rights. There is no sudo bypass for business data.

What happens if two users edit at the same time?

Optimistic concurrency checks apply. With NexGen Gantt Collaboration installed, presence chips and edit locks further reduce collisions.

Which time scales are available?

Hour, Day, Week, Month, Quarter and Year, with zoom in/out, reset zoom and zoom-to-fit.

Can I save my preferred Gantt layout?

Yes. Saved layouts store scale and polish options per user so you can reload your preferred view quickly.

What export formats are available?

Common formats include PDF, PNG, XLSX and JSON. Depending on the installed suite exchange gateway, XML/XER and optional admin-gated iCal may also be available.

Is the UI mobile / tablet friendly?

The shared chrome is responsive. For the best phone/tablet experience install NexGen Gantt Mobile (compact toolbar, touch drag, optional PWA).

Can AI help me reschedule?

Install NexGen Gantt AI Planner. It supports natural-language intents with preview-first apply through adapter validators.

How do I get the full suite at once?

Install NexGen Gantt All-in-One. It pulls Base, all business adapters, Collaboration, AI Planner and Mobile.

Is multi-company supported?

Yes, within normal Odoo multi-company rules. Users only see and edit records allowed by their company and record rules.

Will uninstalling remove my Odoo business data?

Uninstalling a Gantt module removes the module’s menus/actions/helpers. Native Project/MRP/Sales/etc. business records remain.

Where can I ask for customization or support?

Email nexgensolutionsodoo@gmail.com with your Odoo version, module technical name and a short description of the need.

What does NexGen Gantt Time Off do?

It provides a privacy-aware leave timeline for managers to review absences by employee, department, manager, leave type, company or status.

Can I drag leave dates on the Gantt?

Timeline review is the primary mode; date changes go through the native Time Off form so allocation and approval rules apply.

Will employees see private leave details they should not?

No. Reads use standard hr.leave ACLs/record rules, and related labels are returned only when readable.

What do attention markers mean?

They highlight concurrent absences for review — not automatic staffing decisions or approvals.

Which groupings are available?

Employee, department, manager, leave type, company and approval status.

Does Gantt approve or refuse leave?

No. Approve/refuse remain native Time Off workflow actions.

Are public holidays shown?

Public-holiday calendar overlays can be displayed as generic non-working cues.

Can I create a leave from Gantt?

Yes — New opens the native Time Off form so allocations still apply.

Is there sudo access for managers?

No. The module intentionally avoids sudo bypass for leave data.

Can I filter requested vs approved leaves?

Yes — state filters are available.

Does this replace the Time Off dashboard?

No. It is a timeline companion for capacity/absence visibility.

Can Mobile users review leave on tablets?

Yes with NexGen Gantt Mobile installed.

Does Collaboration apply here?

Presence can show who is reviewing the leave board; mutations still go through native forms.

Can AI change leave dates directly?

AI intents still respect Time Off safety — native rules/forms remain authoritative for leave mutations.

What if I lack unlink rights?

Delete is only available when the user has unlink access.
