Hello @dmbantu ,
if you are not a database specialist please don’t do anything.
Ok first of all you have to backup your database.
Here is the datavalueaudit table structure
As you see this table use dataelementid as a foreign key, so you have to know the ID of your dataelement.
Here is the Query to get the ID of dataElement
select dataelementid from dataelement where uid='theUIDofyourdataElement';
Do you how to get UID of your dataElement ? You can get it in Maintenance → Data Element → Action Menu - > Details
Now you can delete values from datavalueaudit based on the dataelementid with the following query
delete from datavalueaudit where dataelementid='theIDofyourdataElement';
