Hi,
As of now , You can do repair full request with proper selections.
Load those two records.Later do the reporting and see.
if there is no issues no problem. if any key fig values are doubled then at cube level you can do selective deletion of old data.
Regarding delta issue please raise to SAP.
Seems like your delta loads will worked based on delta point settings.
based on delta settings will pull the records. if clearing date was changed along with delta relevant fields then changed records will be pulled other wise it won't.
Thanks
