Defines the type of information to retrieve from the population. In the ssan3_info section of the SSA-NAME3 Workbench, under

Mandatory Controls

, you can find a complete list of the supported item types.

For example:

ITEM=key_level

returns all the available values of the

Key_Level

control.

The

SELECT

control is applicable to the following item types:

purpose.list
fieldlen
match_explain_count
field.options

The

purpose.list

and

fieldlen

item types require the

SELECT

control.

The

SELECT

control is optional for the

field.options

and

match_explain_count

item types, and if you do not specify the

SELECT

control for these item types, the ssan3_info call retrieves information about all the fields or purposes.

For example:

ITEM=fieldlen SELECT=CreditCard

returns the key length of the

CreditCard

field.
