Tips and Tricks 11.3
However, it works for you, so you want to keep it. What do you do? You do just
what you would if you had “repaired” a standard SAP program. You use the
Enhancement framework to isolate your change, as described in Chapter 6, and
then when the update happens your change is magically still there.
In this example, go to the standard ABAP2XLSX class ZCL_EXCEL_WOKSHEET in display
mode, and click the Enhancement icon (which looks like a seashell), or press
(Shift) + (F4). Then, right-click the method you want to replace—in this case,
Calculate Column Width—and choose the Insert Over Write Method option
from the resulting context menu, which on ce again is a mix of English and German.
The result is a new column, as seen in Figure 11.16.

Clicking the icon in the overwrite column takes you to a source code editor, in
which you can write some code to to tally replace the standard method. The
replacement method will naturally have the same signature. Delegate the method
call to your own EXTENDER class, which is wher e you can store all your
ABAP2XLSX extension code. The code for this is shown in Listing 11.34.
