When you generate a file list through a command, you select a sample file that
Data Integration
uses to extract the field names.
Data Integration
does not extract data from the sample file unless the sample file is included in the generated file list.
If a file in the generated file list does not contain all fields in the sample file,
Data Integration
sets the record values for the missing fields to null. If a file in the file list contains fields that are not in the sample file,
Data Integration
ignores the extra fields.
For example, the sample file that you select contains the fields CustID, NameLast, and NameFirst. One file in the generated file list does not contain the NameFirst field. When
Data Integration
reads data from the file, it sets the first names for each record in the file to null.
Another file in the generated file list contains the fields CustID, NameLast, NameFirst, and PhoneNo.
Data Integration
does not import records for the PhoneNo field because the field is not in the sample file. If you want to import the phone numbers, either select a sample file that contains the PhoneNo field, or add a field for the phone numbers in the transformation.
