READ TABLE with Subsequent Memory Assignment Check

What is the Intent of the Check?

This check tries to prevent undesired changes to the content referenced by a field symbol. Using an INTO clause with a field symbol overwrites the referenced content when the programmer might have intended to assign the field symbol instead.

How does the check work?

This check searches for READ TABLE statements which use an INTO clause with a field symbol as its target.

How to solve the issue?

Use ASSIGNING instead of INTO in combination with field symbols.

What to do in case of exception?

In exceptional cases, you can suppress this finding by using the pseudo comment "#EC SUB_ASSIGN which should be placed after the closing dot of the READ TABLE statement:

READ TABLE itab ASSIGNING FIELD-SYMBOL(<fs>) WITH KEY key = '1'.
" Do something with <fs>

READ TABLE itab INTO <fs> WITH KEY key = '2'.    "#EC SUB_ASSIGN
" Do something with <fs>
