Execution Type:
You can use the input help to choose between Normal (N), Unscheduled (E), and Repeat (R).
¡ Normal (N): You perform a regular posting run. This parameter is set by default.
¡ Repeat (R): A repeat run is necessary if some of the contracts were not processed successfully during the normal run.

You have
already carried out a periodic accrual run for the key date with normal
execution type.
Errors occurred while the accrual values were being calculated for some of the
contracts.
After correcting these errors, you restart the periodic accrual run with the
repeat execution type.
¡
¡ Unscheduled (E): The periodic accrual runs usually have to be carried out for the key dates stipulated by the posting control frequency in the Accrual Engine. The accrual runs have to be carried out for all of these key dates. The key dates also have to be processed in ascending order.

You have chosen monthly as the frequency. For this reason, periodic accrual runs in 2003 are only possible for the key dates
01/31/03
02/28/03
03/31/03
and so on.
You have carried out a posting run for the key date 01/31/03 with normal execution type. This means that the next run should be carried out for the key date 02/28/03. If you want to skip this key date, however, and carry out the next run for the key date 03/31/03, you have to choose the unscheduled run type.
