Projection VS Aggregation in SAP HANA

Hi All,

Could some one please help me the difference between projection and aggregation while creating a calculation view

a) What is difference between projection and aggregation used to create a calculation view

For me both behaves in the similar way. I used the efashion data to model a calculation view. my calculation view consist of one analytic view which provides me the data for Amount Sold, Article Id, Year and Week Id

If I remove the week id from the output of calculation view then then Amount sold gets aggregated automatically at year level while using a projection or aggregation between the output of calc view and analytic view. If i use week id then the aggregation does not happen at year level immaterial of the fact I use projection or aggregation

Thanks
