DIFFERENCES BETWEEN AT NEW AND ON CHANGE IN SAP ABAP.

DIFFERENCES BETWEEN AT NEW  AND ON CHANGE OF IN SAP ABAP. 

At new should be used inside the loop, but on change of can be used outside the loop also.

At new takes only one field, but on change of can take multiple fields.

Let us assume that an internal table is having f1, f2, f3 , f4 and f5 fields and if  at new is applied on f3 field it will be triggered for every change in f1, f2 and f3 fields, but on change of will be triggered for only changes in f3.
