About Using Pre-Defined Datatypes

Depending on the type of custom field, you may have the option to use a pre-defined datatype.

When using a pre-defined datatype, the system formats the custom field the same as the datatype. For example, if you create a field called ‘Units’ and assign the ‘bUnits’ datatype, the custom field uses the following formatting:

Input Type:


Input Mask:


Input Length:



3 (Numeric

Note: If you plan to implement data level security for the custom field, associate it with a securable datatype. See “Setting Data Level Security for a Custom Field” in Related Topics below.
