LIST ER function

The LIST function returns a Record list value that consists of a new list of records that is created from the specified arguments.

LIST (record 1 [, record 2, …, record N])

record 1: Container (record)

A reference to a data source of the Record data type. This argument is required.

record N: Container (record)

A reference to a data source of the Record data type. These additional arguments are optional.

Record list

The resulting list of records.

The structure of the list that is created contains only the fields that are presented in the structure of every record that is mentioned in the arguments.

You enter data source Record 1 of the Container type. This data source contains the following nested fields of the Calculated field type:

• Code: This field contains an expression that returns a value of the String type.
• Amount: This field contains an expression that returns a value of the Real type.

You then enter data source Record 2 of the Container type. This data source contains the following nested fields of the Calculated field type:

• Amount: This field contains an expression that returns a value of the Real type.
• IsValid: This field contains an expression that returns a value of the Boolean type.

In this case, the expression LIST('Record 1', 'Record 2') returns a new list that contains two records. The structure of this list consists of a single Amount field of the Real type, because this field is the only field that is presented in every argument of the called function.
