Specifying scrambling options for date and time fields

You select a field from the Field Selection/Edit panel. To select a field for specifying date and time scrambling options, enter DT in the Cmd field adjacent to the required field. You can enter DT against as many fields as you like. For each field you select, FM/IMS displays a Date/Time Attributes panel.

The scrambling options you can specify are:

• Scramble type (random or repeatable)
• Start and end values for a date and time range

Specifying the scramble type

Select the Random option to have FM/IMS produce a random date and time output value on each invocation of the copy process. If the Random option is not selected and range Start and End values are specified, FM/IMS performs repeatable scrambling where the same date and time output value is produced on each invocation of the copy process.

Specifying range values

Range Start and End values must be specified for FM/IMS to perform scrambling on the date and time field. The Start and End values must be entered as date and time values in the output attribute Format defined for the field. These values define the range from which FM/IMS can generate scrambled date and time values.
