Standard programs for scheduling batch of IDocs

People

I know there are standard programs that are used to send the Generated IDocs to the Ports at fixed intervals.

These are apparently specific to Transactions.

Eg there will be one for the 810(Invoice)

One for the ASN etc.

So can any one please guide me about this.I need to know the names for a quite a fes types.Including the Rare ones 816(Organisation relationships) and 824(Application Advice).

Regards
