Here’s another fun little tidbit for the new coding in S/4. If you want to concatenate a string together you used need to do:
CONCATENATE ‘X’ ‘Y’ into lv_var.
now you can do:
lv_var = ‘X’ && ‘Y’.
Even better, you don’t run into type mismatches either. For example, if you have a time stamp, the value is in a packed format. This means that you must first concatenate things into a string, then copy them to the final value. with the &&, you can skip all that and do it in a simple one line statement.
ABAP really is getting better
