Replace OOB Business Closures with a Custom Web Page in Dynamics 365 CRM
Dynamics 365 CRM provides an Out-of-the-Box (OOB) Business Closures feature to define non-working days across your organization. However, in many real-world scenarios, we often face limitations with the default interface in terms of customization, UX/UI control, or extensibility.
In this blog post, I’ll Walk you through how you can replace the OOB Business Closures using a custom HTML + CSS + JavaScript web page embedded in Dynamics 365. This custom page will interact with a custom Dataverse table that stores your closure dates and related details.
Why Replace the OOB Business Closures?
Some of the common limitations of OOB Business Closures:
- -Cannot add custom fields like “Reason”, “Department”, or “Applicable Teams”
- -Limited UI customization (e.g., calendar picker, recurring closures)
- -No direct integration with custom scheduling logic
- -Not easily extendable for multi-region closure handling
What We’ll Build
A custom web resource embedded in a Dynamics 365 CRM dashboard or form tab that:
- Lists existing business closures
- Allows users to add new closures via a form
- Uses Dataverse table (e.g.,
new_businessclosure) as the backend
Step-by-Step Implementation
1. Create a Custom Table in Dataverse
- Name:
Business Closures - Schema Name:
new_businessclosure - Fields:
new_name(Text)new_startdate(DateTime)new_enddate(DateTime)new_reason(Multiline Text)new_region(Choice / Text)
2. Create the HTML Web Resource
3. Upload as Web Resource in CRM
- -Go to Advanced Settings > Web Resources
- -Upload the file
businessclosures.html - -Add it as a web resource in the sitemap as a webpage url (like the main form for Settings or a Custom Entity)
Benefits of this Approach
– Fully customizable UI
-Supports additional metadata (reason, region, team)
-Extensible for APIs, workflows, Power Automate, etc.
-Better UX for users with real-time interactivity
To conclude, by using a simple HTML, CSS, and JavaScript front end, we can extend Dynamics 365 CRM to manage business closures in a much more flexible and modern way. It not only overcomes the limitations of the OOB feature but also gives us complete control over the user experience and data model.
