SAP ABAP is a difficult programming language to learn; not only is it old and clunky, but there are also huge barriers to access the only programming environment available for it. To write ABAP programs you have to have a complete and working SAP system, and even professionally managed development systems are difficult to program on due to the lack of data in the systems. I think that this at least partially contributes to the lack of good online reference material. I know that it is possible search the SAP help forums, but the code there often looks like an giant glob of unformatted nonsense. Since I do not have time right now to create a decent site which can explain ABAP to people, I thought I would simply share an example program which shows many ABAP program/report programming techniques all in one spot.

This program should work exactly as it is, the GUI texts would have to be filled in using the development environment of course. Normally a program of this size would be broken into smaller files, and those demarcations are show in the embedded comments. If you read through this program and find something that could or should be handled in a better way, then please let me know.

The code I used should be properly parameterized, so you should be able to simply call it with different table arguments.

PERFORM file_download TABLES gt_data1 USING pa_pfad1.
PERFORM file_download TABLES gt_data2 USING pa_pfad2.
PERFORM file_download TABLES gt_data3 USING pa_pfad3.

You could probably also make something very fancy using field symbols, but the above code is probably preferable due to its clarity.

Hi Christopher,

Thanks for the code. How can I call file_download subroutine again and again with different itabs ?

Is that possible ?
