Let’s start by assuming that you have some dignity and so you don’t use internal tables with HEADER LINE anymore ;)

Given this, let’s suppose you declare an internal table:

DATA: T_KNA1 TYPE STANDARD TABLE OF KNA1.

If you want to read data of T_KNA1 by doing LOOP or READ TABLE, you need to save the read register in a structure or in a FIELD-SYMBOL. Let’s choose a structure.

Traditionally we would declare it like this:

DATA: S_KNA1 TYPE KNA1.

Instead, my suggestion is that you declare it this way:

DATA: S_KNA1 LIKE LINE OF T_KNA1.

The two main advantages of doing so are:

• If the register type changes you just need to update it somewhere;

• It becomes clearer that S_KNA1 is connected to T_KNA1.
