Use of $Projection Keyword and Filters in Association

8061 Views

Hi Experts,

I want to know the use of $projection keyword. when should we use this keyword.

I want to know the difference of below two statements

business_partners[ bp_role = '01' ].company_name as customer_name --

I know this statement is used to display the customer name whose Bp_role value is equal to 01


But I didn't understand the below statement


mard[1: matnr = '0000000010'].lgort


Can you also please tell me about use of associations. Since we can use inner joins in which business scenario we can use associations.


Thanks
