Table values lost in background mode

Former Member — Wed, 29 Sep 2010 16:25:53 GMT

Hello everyone.

I need some help please.

I have a selection screen with a file upload box (AT SELECTION-SCREEN ON VALUE0R-REQUEST.... CALL FUNCTION 'F4_FILENAME'). When I execute the report in foreground, the file is converted and I can get the values for it, but when I execute in background, the file is lost, which is somehow logic. I tried to convert the file values in the same AT SELECTION-SCREEN that I used to get the file from my computer. Now when I directly hit F4 and select the file, the values from the file are procesed and saved in gt_datatab, while the selection screen is still open. Now again if I start the report with F8, the values from gt_datatab are available, but if I start in background mode, the values are lost.

What can I do? I tried all kind of events combinations...

Thank you.

No - the PC is not available when the program is run in the background.

Yes, that's why I used the file processing function in the AT SELECTION-SCREEN ON VALUE-REQUEST, and the table is populated in this block of the program before I hit F9 to go in background mode, but after I go in background, also the values of the table are lost. Why?

Hello,

Instead of uploading the file data into internal table in AT SELECTION-SCREEN events, try doing it in START-OF-SELECTION event.

Means to say, Run the program in background with just the filepath filled. And in START-OF-SELECTION event, upload the data from file.

Hope this helps,

I cannot do that because the path is from my computer, and background mode is starting a job that is independent of the SAP GUI, so it cannot upload the file from the computer.

Hello,

What you can do is that create a variant for the Report in which the file location is specified already.

Now you can schedule the batch job with this variant.

Hope this helps.

Again it doesnt work because it cannot memorize the file data and transfer it to the background mode.

I managed to to succed by using in the block "AT SELECTION-SCREEN ON VALUE-REQUEST" to EXPORT the internal table to SHARED MEMORY, then inside the code that is executed in the backgroud job, I will import from the SHARED MEMORY. It works only with SHARED MEMORY, because this is the only memory that is usable global by all the work processes.
