Alv grid dispaly issue

Hi,

I have developed a alv grid dispaly report where I am showing 8 fields on output.

from these 8 field 7 fields are non editable but one field is editable and when user enter any text it will save these text in a table.

My issue is once user enter any text and it is updating sucessfully but when user open the same alv again the modifiable field comes to clear means the privious text has not display.

But my requirement is once the user enter any text and click on save so it save sucessfully and these text should come again when the user open the program again

means the privious text sshould come again to that editable field and also if user want he can edit the privious text and write some new text and save.

please give some suggestion how i ll solve this issue?

Regards,

Ajit
