When you set up Dynamics 365 Field Service for your organization, you might need to customize the forms that back-office workers like dispatchers and service managers use to view important information and document their work. IT administrators customize Field Service forms to ensure that form layouts match your business processes and let users capture information unique to your business or industry.

Customizing forms correctly is important for maximizing performance. Form customizations affect form load and save times. Proper customization improves usability, making it easier for users to view and update information.

This article explains how to customize the work order form for the web app. However, the steps can be used to customize any Field Service web form. To customize the work order form for the mobile app, go toEdit the booking and work order form.

Step 1. Understand the default work order form

Before you customize the work order form, make sure that you understand the default work order form that is included with Field Service. An understanding of the existing fields and recommended process flow helps you determine what changes to make to the form. For better performance, usability, and upgradability, we recommend that you use the default fields and processes.

1. Go toField Service >Work Orders, and either select an existing record or create a new one.

2. View and familiarize yourself with the default fields, and determine which ones can be used for your business.

   

Standard work order process

The default work order form supports this standard work order process.

1. A work order is created manually, from a converted case, via an Internet of Things (IoT) alert, from an agreement schedule, or via an integration. By default, newly created work orders have a system status ofUnscheduled.
2. Work order details are entered. These details include the account, work order type, location, products, services, service tasks, and any other information that is important.
3. The work order is scheduled to one or more resources (frontline workers). The system status is automatically changed toScheduled.
4. A frontline worker views the scheduled work order on their mobile app and travels to the customer location to perform the required work. The system status is changed toIn Progress. The frontline worker updates information such as the time when they arrived on-site, the service tasks that they completed, and the services and products to bill.
5. The frontline worker completes the work order. The system status is changed toCompleted.
6. The back-office manager or dispatcher reviews the completed work order and verifies that the work was completed and the necessary data was captured. If everything is finished, the system status is changed toPosted.

Critical fields

The following fields are critical to the Field Service work order process and are required. If your organization doesn't plan to use these fields, consider using a different entity/table or create a new one.

• Work Order Number
• System Status
• Service Account
• Billing Account
• Price List
• Work Order Type
• Work Location
• Address
• Latitude
• Longitude

The following subgrids are also critical to the Field Service work order process and are highly recommended:

• Bookable Resource Booking (Bookings)
• Service Tasks
• Products
• Services

Step 2. Make a list of needed and unneeded fields

Make a list of default work order fields that are relevant to your business process. Make another list of unneeded fields. Be sure to add thecritical fields to the list of needed fields, because they are required.

Step 3. Create new fields as needed

If the default work order form is missing fields that you need, create new fields.

To learn about best practices, go toCreate and edit Field Service columns.

Step 4. Start to customize the work order form

Although we recommend that you use the existing (default) work order form that is included with Field Service, there are scenarios where you might want to create a new custom work order form.

The following tabbed sections explain the pros and cons of each approach. They also include instructions for getting started with each approach.

Step 5. Hide form tabs, sections, and fields

Hide unwanted tabs, sections, and fields. We recommend that youhide items instead ofremoving them. This approach helps reduce the likelihood of errors. You can more easily add the items back later if they are needed. Hide items before you rearrange or add fields.

Hide unwanted tabs

Select the Tree view. Tabs appear horizontally at the top of the form. Hide unnecessary tabs. The summary tab can't be hidden.

Hide unwanted sections

Sections are areas on tabs. Hide sections that you don't need. If a section that you need has only one field, move that field to another section, and then hide the unneeded section.

Hide unwanted fields

Hide fields that you don't need, unless they arecritical fields.

Remove price-related fields if applicable

You can easily remove all price-related fields (likePrice List andTotal Amount) from the work order, work order product, and work order service forms.

1. Sign in to the Field Service app.
2. Select theSettings area.
3. UnderGeneral, selectField Service Settings.
4. On theWork Order / Booking tab, set theCalculate Price field toNo. Learn more inWork Order / Booking settings.

Remove tax-related fields if applicable

There is an easy and supported way to remove all tax-related fields (such asTaxable) from the work order, work order product, and work order service forms.

1. In Field Service, select theSettings area.
2. UnderGeneral, selectField Service Settings.
3. On theWork Order / Booking tab, set theCalculate Tax field toNo. Learn more inWork Order / Booking settings.

Step 6. Add your custom fields to the form

If you created custom fields (columns) earlier, add them to the form. For the best outcome, follow these guidelines:

• (Required) Add new custom fields to a new form section.
• (Highly recommended but not required) Add new custom fields to a new form tab.
• Don't add new custom fields to the first form tab unless you must. (By default, the first tab is the summary tab.) Custom fields on the first tab cause form load times to be slower. In particular, avoid adding subgrids and lookup fields to the first form tab, because they can cause load times to be significantly slower.

Add your custom fields to a new form tab (recommended)

In this example, you have a new custom field that is namedSource. It's a choice-type field that is used to select whether the work order originated from a phone call, email, IoT alert, or agreement, for example. You want to add this custom field to the work order form.

1. Sign in toPower Apps.

2. In Power Apps, open the work order form editor.

3. SelectComponent on the toolbar, and then, in theComponents pane on the left, select1-column tab,2-column tab, or3-column tab.

   

4. Rename the tab based on your business process.

   When a new form tab is created, new sections are automatically created on it.

5. Add your custom fields to the new sections on the new tab. You can add new tabs and new sections as needed.

Add your custom fields to a new section (required)

In scenarios where you need custom fields on an existing tab, create a new section on the tab, and then add your custom fields to the new section.

For example, you created a new section on theGeneral tab of the work order form, and you want to add custom fields it.

Step 7. Test your forms with tools

To determine how factors such as browsers, network performance, and data queries affect app and form performance,run performance insights.

For help understanding the root cause of slow form load times, use the monitoring tool. Learn more inUse Monitor to troubleshoot model-driven app form behavior.

Form scripts

The work order form includes script libraries. Don't edit or remove any out-of-the-box form libraries.

When the form is loaded, changed, and saved, many organizations run code scripts to perform validations and run processes. Form scripts can greatly affect aspects of form performance, such as load times.
