l Select All weeks to have the process run every week.
l Select First, Second, Third or Fourth to have the process run on the first, second, third or fourth
week.
l Select Last to have the process run only on the last week.
l Time division: Select the duration of each daily segment in the time grid. If you select 00:15, each
segment will represent only 15 minutes and each day will be made up of 96 blocks (4 blocks per hour
times 24 hours). If you select 24:00, each segment will represent an entire day.
l Poll once per activity period: Select to perform this process’ initial input task no more than once for
each set of contiguous blocks (blocks that are on the top of one another). Choosing this option
overrides the polling interval option. By default since the Time Grid blocks are divided by hours, this
option will make your polling happen once every hour.
The Time Grid
The PReS Workflow Process Options dialog box includes a time grid that lets you set exactly when you
want a process to run. The grid is composed of blocks that represent time periods on a given day. To
activate the Time Grid, the "As soon as possible"option must be unchecked.
In the Time Grid, a blue block will indicate that the process is active within that time block. While blocks
mean the process will not be active.
