If a barcode is used for data capture, it is a field. Create it when you are working with fields. The
Properties dialog box of such barcode has all the tabs of the Field Properties dialog box: General, Data
Type, Recognition, Verification, and Rules. The value of such barcode will be recognized and, if the
settings provide for it, sent to verification and export.
3.1.3. Field Properties
It is important to set field properties correctly, because they affect the quality of field recognition and
define whether the field values are to be exported and sent to the Operator for verification. Some properties
are important for data recognition. For example, the text field marking property is to be set carefully, so
that the marking that doesn’t disappear during scanning is separated from the characters. It will lead to the
recognition resulting in text only, without unnecessary elements.
Correct field properties lead to better recognition results making the Operators’ work easier. When you set
field properties, document verification can be reduced to minimum.
When you have created a field of a certain type, it will have default properties. Some properties are taken
from the Document Definition (for example, language), others are defined automatically (for example,
marking type). They can be changed in the dialog box that opens when you click Properties on the
shortcut menu of any object. Every field type has its own properties.
3.1.3.1. General Field Properties
The Properties dialog box of every field has the General (Figure 3) tab. The Name and description are
specified on this tab. You can change the name automatically given to the field at the creation stage which
corresponds to the comments that are most close to the field. Caption is the field name as displayed as
data. The field type is displayed on this tab as an icon to the right of the name.
Additionally, the following options can be selected on the General tab:
• Export Field Value – clear this option if you don’t need to export the field value. This may be
necessary, for example, if the field value is used to get the value of the calculated field (see Rules
Checking), and you need to export the final result only.
• Read only – select this option to prohibit any changes by an Operator. You may want do select the
option for fields with values to be calculated automatically (according to rules), for example, for
fields where you plan to save a sum or combination of values of other fields (see Rules Checking).
• Show in data form – clear this option if you don’t want the field to appear on the data form when
viewing documents. If an error occurs in such field, you will be unable to correct it in the
Document Editor window, because the field will not be displayed. Thus, it is recommended to
specify the settings that will not cause any errors in such fields.
• Cannot be blank – select this option if the field is required to be filled in. If the field is empty, a
format error will occur.
• Index field – select this option if you are going to index the field. In this case, the field value will
appear for each document in the list, and the Operator will be able to sort and search for documents
by the value of this field. The index field value can also be used for file naming during export.
