 ### How does the check work?
 It searches for `DATA` and `FIELD-SYMBOLS` declaration inside of `IF`, `ELSEIF`, `ELSE`, `DO`, `CASE/WHEN`, `LOOP`, and `WHILE` statements, and for its usage/reference outside this statement.
 
+ABAP lacks of proper scope handling. If a variable is declared in a IF-Block, it should only be used/refered inside this IF-block (not outside). The same applies for LOOP, DO, WHILE or any block structure. In otehr words, it is not allowed the usage of a variable outside the block/scope where it was declared. Thus, it is still possible to make usage of dynamic declarations inside of blocks with a single statement:
+
+```abap
+IF cond = ABAP_TRUE.
+  DATA(MYDATA) = MY_METHOD().
+ENDIF.
+mydata = ABAP_TRUE. "no longer accepted
+```
+
 ### How to solve the issue?
 Relocate the declaration.
