a!recordData( recordType, filters, relatedRecordData, fields )
This function references a set of records from a record type and allows additional filtering in a read-only grid, chart, or selection component that uses a record type as the source. When referencing one-to-many relationships in grid columns, you can filter, sort, and limit that related record set using the relatedRecordData parameter and the a!relatedRecordData() function.

The a!recordData() function is supported within the data parameter of the following components:
This allows you to specify and filter which data is displayed in these components.
The filters parameter allows you to specify which related records are returned using a single logical expression or a list of query filters.
When defining query filters, you can reference record fields or related record fields from the record type specified in the recordType parameter. Use a record field reference or related record field reference to specify the field you want to filter by.
For example, the following expression would display a pie chart with all active employees.

operator: "=",

...
Note: Filters are not supported on service-backed record types without data sync enabled.
The relatedRecordData parameter allows you to filter, sort, and limit the related record sets. This parameter is only supported when a!recordData() is used in a read-only grid, and references a record type that has a one-to-many relationship.
By default, when you add a related record field from a one-to-many relationship as a column in a grid, the maximum number of related records returned for each base record is 10. The list of related records returned for each base record is sorted in ascending order by the primary key value from the related record type.
To change the default limit and sort behavior on your one-to-many related records, you can configure the a!relatedRecordData() function to apply a new limit and sort, as well as filter the related record set.
For example, let's say you have a read-only grid that displays customer information, and you add the related record field orderNumber as a new column in the grid. By default, each customer will have a maximum of 10 orders listed in their row. The orders for each customer will be sorted in ascending order by the primary key field in the Order record type.
To only display the latest order for each customer, you can configure the a!relatedRecordData() function in the relatedRecordData parameter so you can limit the related orders to 1 and sort by orderDate in descending order.
See the a!relatedRecordData() function for additional usage considerations.
The fields parameter allows you to specify when to query the fields referenced in the columns of a read-only grid. Configuring this parameter can improve performance on grids that use dynamic behavior (such as conditional logic) to determine which fields display in your grid.
By default, a grid will query and display all the data specified in the columns, pagingSaveInto, and selectionSaveInto parameters. This default behavior can potentially impact performance if your grid includes dynamic behavior since it may result in querying more data than necessary.
For example, let's say you configured the showWhen parameter on the columns in your grid so that certain columns only appear to managers. Even when columns are hidden from the grid, those fields will still be queried since they're specified in the columns parameter of the grid.
To alter this default behavior, you can configure an if() statement in the fields parameter of a!recordData() to specify that when a manager views the grid, it should only query certain fields. If someone other than a manager views the grid, query a different set of fields.
The expression would look something like this:
Note: When configuring the fields parameter, you must specify all of the fields referenced in the columns, selectionSaveInto, and pagingSaveInto parameters of the read-only grid. Otherwise, those fields will not be queried and, therefore, not appear in the grid.

Record type object references are specific to each environment. If you copy and paste these examples into your interface, they will not evaluate. Use them as a references only.
Let's say you want to create a read-only grid that displays all employees that do not have a "manager" title.
A sample expression could look like this. This expression uses an Employee record type, which has a one-to-many relationship with a Case record type.
