Hi Cleo,
RSKZ must be enough. If you want load this data, you have two ways.
1) Try change your DSO standar to write optimized.
2) Use a routine to change your data.
Regards.
data:lv_string type string.
lv_string = '&^%&^%!@&%hjasdg^%^%@%!aa&'.
REPLACE alloccurrencesofREGEX'[^[:alnum:]]*'IN lv_string WITH''.
write lv_string.
