To learn more about filters in general, see section Understanding Filters.
Use this filter whenever you receive a structured text file. These are the text files in which the fields are identified by one of the following methods:
Fields are delimited by a character: Usual delimiter characters are comma or semicolon. CSV (comma separated values) is a typical example of a delimited file.
Fields contain fixed number of characters: In other words, fields are defined by fixed-width columns.
For examples of structured text data, see section Text Database.
For structured text files, the definition of fields is very straightforward. There are two options:
Delimiter defines the fields: In this case, you have a delimiting character, such as comma or semicolon separating the fields. You just have to define the field names in the same order as they appear in the data received by a trigger.
Fixed-width fields: In this case, define the field names in the same order as they appear in the data received by a trigger, and define the number of characters the field would occupy. That many characters are going to be read from the data for this field.
