How to use ARTNR in the context of SAP S/4HANA Margin Analysis: Attributed Profitability Segment

[AlexanderDomurath]

Hello SAP Community,

I am currently trying to make use of the field ARTNR in the context of the new attributed profitability segments in margin analysis.

Therefore, I maintained respective maintenance order types in this IMG activity:

Subsequently, I populated the settlement rules with the needed PSG information via KEDR. So far, this has worked all quite well. However, I now want to also make use of the field ARTNR (Product) which is displayed in said PSG of the settlement rule: 

Now, the problem is, that ACDOCA apparently does not contain the field ARTNR. I found that ARTNR and MATNR share the same domain (MATNR) but the field MATNR in ACDOCA also remains empty after creating some test documents.

I also found that I am not able to add either MATNR nor ARTNR to my operating concern in KEA5. 

The last option I am currently thinking of, is creating a custom field that is basically a copy of ARTNR and defining a Move via KEDR to transfer the ARTNR value to the new custom field.

As this last mentioned idea seems a bit odd to me, I would like to ask if someone has encountered similar problems and/or can maybe share a solution approach.

Thanks in advance

Kind regards

Alex
