Configuring the VRL group subfield properties

Each field of the group is composed of one or more subfields. Subfields contain the actual data within the record. The subfields of a field are the same as the subfields of a record-layout data field.

  1. To create a new group subfield, select the field folder in which to place the new subfield and click New Subfield.
  2. For Data Type, click the arrow to select from a menu of data types.
  3. For Prefix, specify the characters that precede this subfield. This separates it from the previous subfield in the record layout. This value is optional.
  4. For Postfix, specify the characters that follow this subfield. This separates it from the next subfield in the record layout. This value is optional.
  5. For Min Width, specify the minimum width of the subfield, not including any prefix.
  6. For Max Width, specify the maximum width of the subfield, not including any prefix. To disable, specify a value of -1. This is the default. For a specific width, specify the value. Incoming data larger than that value is truncated.
  7. For SSF Sep, specify a subsubfield-separator character.
  8. For validation, select how to validate the subfield data whenever this record layout is used as an input or output record.
    Existence validates the existence of the data, but not its content.
    Contents validates the type of data, but not its existence.
    Existence and Contents validate both the existence and the content of the data.
