download space character

Dear all,

i meet a problem: i want to download report data in internal table by FM WS_DOWNLOAD,and this internal's last column is space (length 8). but i can't remain the last column space in local text file after download.

ex. AAAABBB________ --> internal table (ok)

AAAABBB --> download to local text file (NG)

how can i remain the space character in text file by download? or other way to remain it?

TKS

Regina
