Hi Guys

I am new to ABAP.Ive mistakenly delted all the records of table KNA1.

I got other system where the same version is installed.

How can I take backup of the table from one system to another

We are in beginner level and now just learning ABAP. We don't know how to restore it. When we are running a program with select options, it deleted all entry's in KNA1 table. Please help me how to restore it by a beginner level student. Thanks in Advance.

how did it allow you to delete all the entires...

in the other system u need to right a code to download all the entries into a flat file and in the system u need to right a code to upload entires..

select * from KNA1

into table it_kna1.

use gui_download to put into flat file.

in the target system

use gui upload to upload into a internal table say itab_target.

and say modify kna1 from itab_taget.

all the internal tables need to be of the structure of kna1..

award points if usefull.
