You’re offline. This is a read only version of the page.
I have a dataverse table that a user will load about 80k rows to per month via a data flow.
Occasionally they will load data that later needs to be removed and reloaded with fresh data.
So, what I need to be able to do in this situation is to automate the removal of the previous version of the data, then triggering the data flow to load the new data.
I haven't been able to find a way to do this with any level of efficiency. I would hope that this many rows could be deleted in just a couple of seconds, but I've only been able to do it in PowerApps using "RemoveIf" and that takes 10 minutes just to remove 2k records!
Please help!!
Hi
If you still need help with this issue I can help.
I know this is a bit of an old thread however I recently had a similar challenge. I got around it by using a staging table with the 'to be validated' data. The data flow was set to 'Load to Existing Table' with a composite key and set to 'Delete rows that no longer exist in the query output'. This ensured that staging table only contains the latest imported data. Once validated this staging table is then uploaded to the history table. This way there is no deletion of records required : -) and only validated data is loaded to the confirmed historic dataset.
Thanks for this.
Your phrasing makes me think that I'm using Dataverse incorrectly.
"If you truly need to automate this"
I have a user who needs to load data, then it needs checking by superiors, and more often than not it will be rejected and need to be reloaded (with changes). That reload will require the original data to have been deleted first to avoid duplication.
Is this an unusual process for dataverse? Is it expected that the dataverse only ever has data written to it and never deleted?
Hi @Andy3,
You can do a Bulk Deletion Job like @rampprakash mentioned in an ad-hoc need. If you truly need to Automate this along with loading other data in a flow, you can use the Call an Unbound Action using the Dataverse connector. There is a BulkDelete action available in the list. You will have to use some JSON syntax for some of the parameters like filtering and such which can be a bit tricky.
Here is an article that walks through an example though which should help you.

3. Click Settings --> Click System Jobs
4. Click More Action
