I wanted to add a new table

I added a Warranty table

I noted that by default the name column was a 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

I noted that adding the Account Lookup column created a new Many-to-one relationship

I added a Many-to-one relationship (Column) for Product (record)

I updated the Main Warranty form

I noted that 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 included a Warranties tab

I created a new Warranty (for the current Account) using the + New Warranty button

The Account was automatically filled in

I entered the Start Date, selected a Product and clicked the Save button

The new record was saved with the name "warranty-100000"

The Warranty was shown in the subgrid
