Hi,

The keyword DEFAULT in CORRESPONDING ... MAPPING gets lower cased when using ABAP Cleaner. Pretty Printer would then upper case it again, if you use it after ABAP Cleaner.
The following code:

FINAL(p1) = VALUE I_Plant( Plant = '0001' ).
FINAL(p2) = CORRESPONDING I_Plant( p1 MAPPING PlantSupplier = DEFAULT '1234567890' ).

gets formatted by ABAP Cleaner to:

FINAL(p1) = VALUE I_Plant( Plant = '0001' ).
FINAL(p2) = CORRESPONDING I_Plant( p1 MAPPING PlantSupplier = default '1234567890' ).

I've used the latest ABAP Cleaner version 1.5.3 with the default profile.
