Hello experts,

I was write this code in include 'ZXV56U18' :

READ TABLE i_xvttk_tab INTO ls_xvttk INDEX 1.

IMPORT ls_voyage-voyage FROM MEMORY ID 'SIG'.

MOVE ls_voyage-voyage TO ls_xvttk-signi.

MODIFY i_xvttk_tab FROM ls_xvttk INDEX 1 TRANSPORTING signi .

When i push my custom button in VT02N and go to my transaction , i transfer value to fields "VTTK-SIGNI"

with export command, and after this , in user exit "EXIT_SAPMV56A_001" i was update this value with import command

like i show below.

When i return to vt02n i see the new value on the screen ( vttk-signi(old) = 'AAA'

vttk-signi(new) = 'BBB' ) , but when i push on 'SAVE' button i get this message:

"Saving not necessary: no changes were made".

Why this is happend which i change the value of this fields ?

Thanks for the help.
