ODS process chain

Question: Hi BW gurus,

When I create a process chain its giving a warning that change run is not scheduled after data load into the ODS.
Do I need to have change run process after ODS data load??? I think change run is needed only after master data loading. what is the purpose of including a change run after data load into an ODS.

thanks in adv.
mfb.
