READ TABLE with Subsequent Memory Assignment Check

What is the Intent of the Check?

This check aims to prevent undesired changes to internal tables using field symbols in context of the READ TABLE statement with INTO instead of ASSIGNING.

How does the check work?

This check finds READ TABLE statements which use statement INTO for assignment but using a field symbol instead of a variable.

How to solve the issue?

Use ASSIGNING instead of INTO in combination with field symbols as otherwise the selected table row will be overwritten.

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>) WHERE key = '1'.
" Do something with <fs>

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