In DELTA-TIME, UNITS is the unit of time denoted in QUANTITY. You can
set UNITS to D (for days), H (for hours), or M (for minutes). To specify one
day, for example, set QUANTITY to 1 and UNITS to D.
LATEST-DELIV-DATE
is the latest date at which the TRANSFER delivery system can deliver the
package. You must specify the date as an absolute calendar date or as a
number of time units from EARLIEST-DELIVERY-DATE. An absolute or
relative date is indicated by the REL-DATE-LATEST field.
EXPIRATION-DATE
is the date on which the package expires. On this date, the package is
automatically removed from the INBOX of any recipient who has not already
acknowledged its receipt through the ACK-RECEIPT UOW. Packages that
either are acknowledged or are in other folders are not affected by expiration.
Any copy of the package kept by the sender must be explicitly discarded by
the sender, or the TRANSFER delivery system waits for the item-retention
time to elapse before removing the item. A relative date of value 0 M means
the package will not expire.
If a package expires and the recipient has not acknowledged its receipt, the
TRANSFER delivery system removes the package from the INBOX and
notifies the sender. Packages that are acknowledged by the recipient are only
removed from the INBOX folder by the TRANSFER delivery system when the
item-retention time for this folder elapses; they must be explicitly removed by
the recipient.
By initial system default, TRANSFER packages do not expire. You can specify
that a given package should eventually expire by including a nonzero absolute
or relative expiration date and time in the package header. You can change
the default for your depot by specifying a nonzero relative expiration time in
your correspondent profile. This value must be within the maximum lifespan
as indicated by a TRANSFER system control parameter. If you submit a
package with a nonzero expiration date, the TRANSFER delivery system
increases that field, as necessary, so that it exceeds the configured minimum
expiration date.
The interval between the LATEST-DELIV-DATE and EXPIRATION-DATE is
the package expiration time window. You can specify the EXPIRATION-
DATE as an absolute calendar date or a number of time units from LATEST-
DELIV-DATE. An absolute or relative date is indicated by the REL-DATE-
EXPIRATION field.
PRIORITY
is the package priority. The field can have a value from 0 (lowest priority) to
199 (highest priority).
