In the Sterling B2B Integrator
Map Editor,
double-click an existing field or create a new one.
In the appropriate Properties dialog
box, click the Validation tab.
From the data-type list, select String.
From the data format list, select Free Format. The
drop-down list becomes an editable text box. Free Format indicates
that any characters are acceptable in the field. The translator does
not check the characters for compliance.
In the text box, type the complex syntax for this field.
For example, this enables you to define a complex syntax such as 3a[2!n],
which indicates that the String should consist of zero to three uppercase
letters followed by an optional two digits.
