Process chain errors

Hi all,

I have a question regarding the 'process chain'. Here is my business scenario:

--<b>I loaded data into ODS and then loaded from ODS to the Cube.</b> I created the infopackage for ODS with the 'full load' and 'immediately load' one month ago. Now I tried to create the 'process chain' for this infopackage. However I got an error message-process loading has no preprocessor. Do anyone know why?

--In this scenario, when I created one infopackage for ODS, do I need to add the cube in the 'data target' tab of the scheduler? If not, can anyone tell me how can the cube upload data periodically?

Thank you for whoever share the experience.
