An entity cannot be deleted while dependent Entities for a processing group exist.

Sometimes you need to delete a data object from the main data object. Sometimes this is annoying because it is specified in a data project and you need to delete this report before you can delete the master data. Sometimes you have to go through hundreds of data projects and it's very annoying.

So, Go to the Data entity page, find your data entity and click on processing group linked.

Now select the processing group and delete the references of the targeted entity.

You can delete the entity, Once all the references are removed.
