2LIS_06_INV Extractor Delta Before Image and Reverse Image

Hi All,

I am using the logistic extractor 2LIS_06_INV for extracting Invoice verification data. According to my knowledge the extractor gives ABR (After, Before & Reverse Image) delta.

But when I am trying to extract delta it just show me only the after image. And when an invoice is deleted it shows ROCANCEL as 'D'. But when an invoice get cancelled still it comes as blank. Below shown values are provided in the drop down I get for ROCANCEL in RSA3. Does anyone have any idea of the way delta comes in this extractor?

My question is why it doesn't show the before image and reverse image?

Regards,
