The maximum trust (starting trust) is the trust level that a data value will have if it has just been changed. For example, if source system X changes a phone number field from 555-1234 to 555-4321, the new value will be given system X’s maximum trust level for the phone number field. By setting the maximum trust level relatively high, you can ensure that changes in the source systems will usually be applied to the base object.

The minimum trust is the trust level that a data value will have when it is old (after the decay period has elapsed). This value must be less than or equal to the maximum trust.

Specifies the units used in calculating the decay period—day, week, month, quarter, or year.

Specifies the number (of days, weeks, months, quarters, or years) used in calculating the decay period.

Decay follows a pattern in which the trust level decreases during the decay period. The graph types show these decay patterns have any of the following settings.

By default, the start date for trust decay shown in the Trust Decay Graph is the current system date. To see the impact of trust decay based on a different start date for a given source system, specify a different test offset date.
