Calling Background job - transferring files or internal tables

Hi friends,

The scenario is:

Folder -

-

---

-

-

---

Reading mode

-

-

---

Update mode

where reading mode and update mode are radiobuttons.

If Reading Mode is selected:

Folder (on my PC)

contains many excel files which have to be checked and error records displayed

If update mode is selected:

Program should select the excel files in the

Folder (on my PC)

Ø check the fields in them based on some checks, append, say, itab_error, itab_correct

Ø Using itab_correct to run BDC

Ø Using a Ztable after the above BDC

Ø Give final display list with the itab_error table entries and error records from BDC and Z table update

This BDC and Z table update should be run in background. (or the whole update process including the checking of file should be run in background)

<b>How to go about this background job?? How to pass the internal tables (itab_error and itab_correct) or how to pass all the excel files to this background job??</b>

Advance Thanks
