Process Chain - start up.

Hi,

I am an old-fashioned BW practitioner who worked in version 2.x and then 3.x. New to the new functionality available in the latest version.

Now, I think I need to pick up the knowledge on "Process Chain". I have gone through some concepts at the SAP Help Page ( http://help.sap.com/saphelp_nw04/helpdata/en/80/1a64e0e07211d2acb80000e829fbfe/frameset.htm ) but still got a bit confused on actually where to start in the system. Can someone please give me some help on this? Thanks.

[Would also greatly appreciate if any one can also provide some insights to my other question posted on the forum:

<b>Delte InfoCube data when loading from ODS</b>

problem with delta update on customised export data source.

Thanks a lot!
