Catch click event in BSP-page (web interface)

[Former Member]

Hi Folks!

In my Web Interface, I have created a planning function button of type user-exit. The function does a file upload. When the user clicks on the button I need to do a few checks in ABAP (before the actual function executes). Question is... where exactly can I catch the click-event and do these checks?

I tried a few things with the generated bsp-app in se80, but nothing seemed to catch the click event.

Thanks a lot in advance for your input!

Hi Simon,

the (upload) function is already an ABAP exit. So you can just add your checking logic to the INIT part of the ABAP exit function.

Hi Marc,

thanks for your reply. Actually, we want to export the contents of the file to ABAP memory even before the init function is called. To do this, we need the http request object in context. This is not available in the init function. Therefore we thought the best place to do this would be in the On-Input-Processing event of the generated BSP application in the event 'OnClick' of the button.

Regards,

Simon

p.s : We are using the standard How-to paper to do this but we have locking issues with this solution. Therefore this workaround.

Simon,

I suggest to resolve the locking issues instead of doing a lot of custom development. The web file upload how-to paper is based on a ad-hoc planning package. Therefore, if multiple users try to upload data at the same time, you have to set the selection criteria of the ad-hoc package accordingly. This is already foreseen in the how-to paper (chapter 11.4 OnInputProcessing CALL FUNCTION 'API_SEMBPS_ADHOCPACKAGE_SET'). Typically you can derive the selection criteria from the file content. Alternatively you might include other input fields on the BSP to specify the criteria.
