Margin analysis quantity field revaluation after S/4 Hana upgrade

[miro]

Dear experts,

My name is Miro and I am a new member in this community. I am active as the SAP CO/IM/PS consultant and would kindly ask you for help in specific topic in S/4 Hana Margin analysis.

By the client we have executed the S/4 Hana upgrade to S4CORE 107 version. Before upgrade was implemented change in standard code by the billing document posting as per OSS note https://me.sap.com/notes/118125. With this change the system took over COPA the sold quantities not from the field Sales quantity FKIMG but from the additional quantity field FKLMG. FKIMG is in UoM PC and FKLMG is in UoM KG. After the upgrade the change as per OSS note above was reversed back to standard with the field FKIMG. We have realized that change only after some days which means that in COPA Margin analysis was not correctly for huge number of SD invoices generated quantity field with PC and not with KG. We have implemented this code change as per OSS not above again but of course already posted documents were not updated with the correct quantity field and UoM. So these documents are still with PC which is not requested.

The customer wants now to somehow "regenerated" these already poste not correct documents with the correct quantity and UoM. Is there a way how to regenerate/revaluate these docs in order to get quantity in KG as it was before upgrade? I want to kindly express that we are working with Margin analysis, so the only FI and CO document is generated. So the solution f.e. with KE4S (valid for costing based COPA) does not work for Margin analysis.

Thanks a lot for your valuable answers.
