Availability Time Planning and Polling Interval

Hi ,

I have few interface scenarios ( JDBC Sender / File Sender etc ) which needs to be scheduled 2/3 times a day with predefined time .

For example , JDBC sender sould read the external data base 2 time a day

1. 1:00 AM in the morning

2. 1:00 PM in the afternoon.

I wanted to know what is best way to schedule it ?

Should I create two ATP entry in the defined time , add same Communication Channel in both the ATPs without any polling interval.

Please suggest.
