Generic datasource

Hii,

When I am creating generic datasource, two checkbox are available "safety interval upper limit and safety interval lower limit" in geneic dalta option.

1.Can I choose both the options??

2.If I will choose both the options then to which acquisition level(cube,DSO,info object) data will load?

3.if I will choose one option then to which acquisition level(cube,DSO,info object) data will load?

Thanks in advance.
