Contract Start and End Dates
Start dates can be defined at various levels of a contract: the header, default end users or items, detail lines, and additional charges. Start dates defined at one level default to the level below and determine the valid range for lower-level dates, including limit effective dates. All dates must be within the start and end range defined by the header.
In many situations, the start dates on all levels of the contract are synchronized. If you change the start or end date on the contract header, you are prompted to apply this change to each line item.
When you respond Yes to reset the line start dates after changing the header start date, the system updates all lower-level dates that match the old start date. This includes end user and default item dates, as well as detail lines. When the system updates end dates, it modifies the lower-level dates to reflect the contract end date, regardless of whether the dates previously matched.
Note: Limit effective dates are not automatically reset; you must do this manually, as needed.
If the changes are not automatically applied to each line, the system verifies that the new header start or end date is not within the range defined by the earliest line start date and latest end date. If it is, the system displays an error message.
There are some limitations on changing contract start and end dates:
If any open calls reference the contract, the contract start date cannot be moved after any call open date. Correspondingly, the contract end date cannot be moved before any call open date.
If billing has occurred, you cannot change the contract start date. The end date cannot be set prior to the end date of the coverage period billed.
