Chapter 4: Field Settings
Read Only
When the Read Only option is selected, the user does not have the ability to enter data in the selected field. This is commonly used in conjunction with default values and Variable type fields.
4.2.3Validation Field Settings
Validation Field Settings allow the user to exhibit controls that check the accuracy of the entered data.
AccuScan Settings [Validation]
Validate Immediately
This option represents whether or not a field should be validated immediately after it is entered. When Validate Immediately is not selected and Validation settings do exist, the field data will still be validated when the record is submitted.
Unique Within Record
When selected, this option prevents duplicate data values within the current record. If a field is submitted and it violates the Unique Within Record setting, an audible alarm and error message is displayed.
Unique Within Table
When selected, this option prevents the user from entering duplicate data within the entire session for this field. This does not prevent the same data from being entered into another field within this session, however. If a field is submitted and it violates the Unique Within Table setting, an audible alarm and error message is displayed.
Min Len
This option allows the user to validate an entry based on the minimum number of characters required. If a field is submitted with less than the “Min Len” setting, an audible alarm and error message is displayed. Setting a Min Len of 1, for example, prevents the user from leaving that field blank.
Max Len
This option allows the user to validate an entry based on the maximum number of characters allowed. If a field is submitted with more than the “Max Len” setting, an audible alarm and error message is displayed. Specify a Max Len of zero to disable this rule. Fields in AccuScan Palm can store up to 30 characters.
4.2.4After Scan Field Settings
After Scan field settings are designed to increase data entry speed and accuracy. Repetitive data capture scenarios such as inventory audits lend themselves to the efficiencies of these settings. It is recommended that these features be activated whenever possible.
