SAP api call to store preferences...

Hi, I'd like to know what SAP provides to store user preferences or configurations? For example, in the Vignette portal, I saw an api call like:

<b>preferences.store();</b>

After this call, the user preferences will be stored somewhere in Vignette.

Does SAP provide a similar api call? If so, can you provide a brief example?

Any suggestions or response are greatly appreciated!

Thanks so much for your help,

Baggett
