you try like this.
TYPES : BEGIN OF ty_test,
field1 TYPE char4,
field2 TYPE char4,
field3 TYPE char4,
field4 TYPE n LENGTH 5,
field5 TYPE char4,
END OF ty_test.
data : lt_test TYPE STANDARD TABLE OF ty_test,
ls_test TYPE ty_test.
*&For Aggregate values create a table with only required fields
TYPES : BEGIN OF ty_aggr,
field1 TYPE char4,
field2 TYPE char4,
field4 TYPE n LENGTH 5,
field5 TYPE char4,
END OF ty_aggr.
data : lt_aggr TYPE STANDARD TABLE OF ty_aggr,
ls_aggr TYPE ty_aggr.
LOOP AT lt_test INTO ls_test.
MOVE-CORRESPONDING ls_test to ls_aggr.
COLLECT ls_aggr INTO lt_aggr. "You will get the field4 aggregate
