, and then select Manage User-Defined Types.

The Manage User-Defined Types: <system name> window appears.

Select New Type, and enter values as described in the following table.


Field	Description
TYPE NAME	Enter a name for the user-defined data type (UDT).
DESCRIPTION	Enter a description for the UDT.
ADMINISTER GROUP	Specify the Windows Security Group that you want to assign to the UDT.
DATA QUALITY	Select one of the following options: Store Individual Quality: Select this option to store field-level quality. Storing individual qualities consumes more disk space. Store Master Field Quality: Select this option if you want to assign the same quality as the master field to all the other fields in the UDT. If you select this option, the data sample will have a single quality similar to how an array tag works.
MASTER	Select the radio button corresponding to the field that you want to set as master. When you do so, the data type of this field is used for all the remaining fields in the UDT as well. Only one field can be the master in a UDT. The MASTER column appears only if you select Store Master Field Quality under DATA QUALITY.
NAME	Enter a name for the field.
DESCRIPTION (under FIELD)	Enter a description for the field.
DATA TYPE	Select the data type for the field. If you select Store Master Field under DATA QUALITY, and if you set this field as master, the data type of this field will be applied to the remaining fields in the UDT as well.

For each field that you want to create, select Add Field, and provide the required details.

Select Save Type.

If needed, add more UDTs, and then select Done.

The UDT is created.
