Root Cause: This is a result of a change in behavior on the SAP side. R3_Modify_Variant does initialize values of fields.
Update to a fix version listed below or a newer version if available as it provides a workaround to the SAP bug.
Attached to this article, are some important SAP notes. These notes should be forwarded on to your SAP Basis team. They will need to verify and apply the information from the notes, if they haven’t been implemented already. Pay particular attention to SAP note 2255978, as this has caused issues with the variant modifications in the past.
The notes have been provided in German, but there is a link within the documents to the original online source for English.
