I found two different types of approaches of using SELECT-OPTIONS in an AMDP method as follows. Please help me with understanding the difference and significance.
<int_tab1> = APPLY_FILTER ( <database_table>, :<sel_opt> ).
<int_tab2> = select ... from <int_tab1>
select ... from <db_table> into table @(int_tab1)
<int_tab2> = APPLY_FILTER ( <int_tab1>, :<sel_opt> ).
Thanks in advance.
