Help with Before Image - Postive Values?

[sap_cohort]

Hi, I'm struggling with some values being incorrect in my ODS. I have a current order with 1 order qty and 1 confirmed qty. The order was created back in the beginning of the year and just recently got confirmed.

In BW ODS it shows 1 order qty and 0 confirmed qty. Which is incorrect.

From everything I have read about ABR the Before Image Values in the change log should all be negative. This is the sales item LIS extractor 2LIS_11_VAITM.

When I look at the Before Image Record I see the order qty as negative 1(fine), but the confirmed qty is positive 1? ( I would have thought the confirmed value should be zero in the before image). How can the

Before image record have a positive value?

When I look at the After Image Records I see the order qty as pos 1 (fine) and confirmed qty is 0( I thought this should be 1).

Can anyone help me out with this scenario?

1. Why would the Before Image have a positive 1 for a confirmed qty?

2. Why would the After Image have a 0 confirmed qty if the confirmation generated these records?

Change Log Records
                   Order Qty     Confirmed Qty
Before Image       -1                1
After Image         1                0

Thanks!

Hi,

Confirmed quantity can be negative in case of return I think.

Before images are the opposite sign not necessarily negative values.

So this does make sense.

Thanks for following up. No returns in this case. I have noticed quite a few records with positve key figure values in the before image. Any other explanations?

I'm curious why SAP doesn't document this process more thoroughly..
