Enhancement VA06 - SD_OSO_MONITOR - selection fields

Hi,

I wanted to enhance the new VA06 transaction with new selection fields and also ALV fields. I created an implementation of Badi SD_OSO_MONITOR and added some standard fields like KNA1-KONZS and VBAK-VSBED to the ALV and that worked fine.

Now I wanted to add these fields as selection fields in the tab "Enhancements". I wanted to add selections like in the first screens, but I can't get it running. Either I don't see the fields or the fields are visible, but I am not able to retrieve the values entered.

How exactly do I need to create the dynpro/subscreen?

Thanks in advance for any help.

Regards

Stephan
