Appending two files

[Former Member]

Hi,

I'm trying to write an ABAP program that asks for 2 text files (A.txt and B.txt) from the user. These two files will come from the frontend (Windows C:\Temp folder). I'm planning to append the two files together into a third text file (C.txt) and save it back to the C:\Temp folder on the frontend. Can someone point me in the right direction for this?

Any help is appreciated. Thanks.

You can run FM GUI_UPLOAD twice to upload the files. Then in the program combine them and finally use GUI_DOWNLOAD to write the file to the PC.

Thanks to both of you. What you suggested worked!

I called GUI_UPLOAD twice, appended the contents of the itabs to a third itab and used GUI_DOWNLOAD to save it back to the frontend.

Thanks again.

Hello,

For first intertable tab1 you use GUI_UPLOAD FM.

second internal table tab2 you use same GUI_UPLOAD.

Then create the Third structure with all the fields or TAB1 and TAB2. then move all the records to Third internal table TAB3.
