Hi sumank2997425,
We do not have a way to delete data which has entered Analytics.
That said, there are some workarounds which sometimes are suited to specific cases, for example if you have fired some revenue value which is more than actual conversion, then you may upload a Data Source file with revenue in negative, so as to reduce the originally uploaded revenue value.
Or, in case of GDPR requests you can delete some user specific data - if you have mapped it correctly in Experience Cloud.
However, if your situation does not fall in either of the two conditions and you necessarily need to delete the data as it is hampering some important experience or is business critical, then you may reach out to Adobe Consulting Team - who may help explore possibilities, this will be a paid engagement.
Best,
Utkarsh
