Edit PSA results in CAPITAL letters

Question

We import data from non-SAP systems and occasionally they contain erroneous data.  We edit the PSA to make the correction and then reload.  Unfortunately we have encountered a side-effect - the character string fields are all converted to capital letters (even though lowercase is allowed).
Any suggestions on preventing this would be appreciated.

Hi Ian,
you can try the following in the start routine of your transfer rules:
data: l_allowedchar type rsallowchar,
      l_allchar(200) type c,
      l_uppercase type syabcde,
      l_lowercase(26) type c,
      l_strlen type i,
      l_replchar type c value space,
      l_count type i,
      l_index type i.
select single allowchar into l_allowchar
from rsallowedchar.
l_uppercase = sy-abcde.
translate l_uppercase to upper case.
l_lowercase = sy-abcde.
translate l_lowercase to lower case.
concatenate l_allowedchar l_uppercase l_lowercase '0123456789' into l_allchar.
loop at datapak into l_s_datapak_line.
l_index = sy-tabix.
now, for each field you want to check
if l_s_datapak_line-<field name> cn l_allchar.
the field doesn't contain only allowed chars
l_strlen = strlen(l_s_datapak_line-<field name>.
l_count = 0.
do l_strlen times.
l_count = l_count + 1.
if l_s_datapak_line-<field name>+l_count(1) na l_allchar.
  l_s_datapak_line-<field name>+l_count(1) = l_replchar.
endif.
enddo.
endif.
modify datapak from l_s_datapak_line index l_index.
endloop.
Please check it carefully, I was writing this just from memory without any abab syntax check ....
But in general it will replace not allowed characters with space.
Hope this helps!
