How to remove the space in the info object level?

Question

Hi,
I created a Master Data info Object and gave the data type as <b>Char</b> and length as <b>30</b>.
From the source system I am getting the data of length 9. But at PSA level I am getting some erroneous records.
Example: Data from the source system  'a12345678'
               Data in PSA 'a12345678b'     -
***  where b  - Blank
With out changing the length how can I remove the spaces (Blank)?
Can any one suggest me how to remove, where and what to apply ?
I need to do any settings at the info object level or at the Transfer Rule?
Please provide the each and every step to resolve my problem.
Thank you

Hey  you can allow space in RSKC tcode and execute it... .that's it .
and below is the routine for invalid chars and you can have this in update rules ..
data: w_fielda(x) type c.
data: w_result(x) type c.
data: w_temp_field(1) type c.
data: w_count type i.
w_fielda = COMM_STRUCTURE-/BIC/Zxxxxxx.
w_count = 0.
do x times.
clear w_temp_field.
w_temp_field = w_fielda+w_count(1).
if w_temp_field CA
'!"%&''()*+,-./:;<=>? _0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'.
w_result+w_count(1) = w_temp_field.
endif.
w_count = w_count + 1.
enddo.
