If you want to do so, with M-Business Client 5.0 and later you can create a form that causes only the channel's forms or M-Business XML conduit to be synchronized. The HTML below shows how to do this.

<form type=post action=agreserved://limitedchannelsync> 
<input type="any" name="channel_id" value="channel_database_id"> 
<input type=button name="Submit" value="Sync" onClick="avantgo.beginSync();"> 
</input>
