I used https://make.powerapps.com to add a Warranty table to Microsoft Dynamics 365 Sales.
I added the customization to my Sales Customizations solution.
I wanted to add a new table
I added a Warranty table
By default the name column is required single line of text
I updated the name column to be an autonumber
I added a required Start Date column
I added an End Date formula column
End Date would be calculated to be 3 years after the Start Date
I added an Account (record) Lookup Column
Adding the Account Lookup column creates a new Many-to-one relationship
I added a Many-to-one relationship (Column) for Product (record)
I updated the Main Warranty form
Initially the Main form only included the Name and Owner columns
I moved the Owner Column to the form header and removed the Name column. I added the Start Date, End Date, Account and Product Columns
I updated the Active Warranties view
I added the Start Date, End Date, Account and Product Columns to the view
I added a 1-column tab to the Account table's Main form
I renamed the new tab "Warranties"
I added a subgrid to the new tab
I updated the Labels
I Saved and Published my changes
I added the Sales Trial app to the Sales Customizations solution
I added a Dataverse table page
I selected the Warranty table
I published my changes
The Sales Trial app now included a Warranties page
The Accounts page includes a Warranties tab
I can create a new Warranty (for the current Account) using the + New Warranty button
The Account is automatically filled in
I entered the Start Date, selected a Product and clicked the Save button
The new record is saved with the name "warranty-100000"
The Warranty is shown in the subgrid
