LOOP AT table with a Reference Variable

[kendel]

Hi Everyone. I'm an ABAP student having a problem to understand the logic when looping a table with a Reference Variable that have different ways to print. Why the figure I just upload when the work area is different to the reference Variable that call de method (get_attribute) the print logic is to get de value assigned to that reference variable 3 times (same lines), but when the work area is the same that the reference variable it prints

 

all of the correct values of the 3 different reference variables?. Thanks a Lot in advanced.

Hi,

in the first Loop, the actual values are stored into var. But inside the Loop you reference on the variable num. This holds the last value which you assigned to num. 

To have all the different values you need to use var->get_attributes instead of num->get_attributes.

Hi MBartsch71,thanks for your time, that is a good option, but as I ask, when the work area is the same as the variable reference that call te method get_attributes the result is the exactly the same, in other words when I use "INTO var" with "var->get..." , "INTO num" with "num->get..." Or "INTO connection" with "conncetion->get..." With all of them I recieve the same result as You SEE in the second loop of the image. I am trying to understand the logic of the loop. Why if i put as a variable "num" (work area) and variable reference num to call the method "get attribute" it give me as result the three flights connections store in var, in num and connection.
