Dynamics - can I bulk delete *.csv of matching emails

(0) ShareShare
ReportReport
Posted on by 523

I have a CDS database which needs reconciliation with another database. My present reconciliation has identified 2500 contacts which need deletion from this CDS database. I have a *.csv file containing the emails of all those individuals who need deletion.

Is this a way to do a deletion like this in bulk?

    Hi again @Medoomi 

    I would suggest editing  your data from Dataverse in Excel and doing it from there using Power Query and then reimporting the data.

    Hi @Drrickryp  & thanks so much for your reply.

    Do you mean opening the table in Excel "Edit data in Excel?"

    I am a little worried that my cell count exceeds 100,000...

    Would there be a better option in that case?

    The latest version of excel can handle 1 million rows.

    Just to double check... as I'm still hitting the 1,000,000 *cells* refresh limit.

    I understand I could use filters to get under that number, but to understand the process, do you mean that I process data in Excel (PQ) outside of the data connector (i.e. on a different sheet), and then reload (delete & replace) the entire table with the new data? I am feeling a little nervous about how destructive a process that could be if something failed...

    As an alternative, I'm wondering about uploading the table of emails used to delete contact records into Dataverse & creating a flow that will set a column value for matching records in the contacts table eg. flagged "delete", which I can use as the basis for a Dynamics bulk records deletion... But again, I'm unsure if Flow will be able to handle the amount of processing this will involve...

    As always, I'd appreciate any input/thoughts, thx!

    Hi @Medoomi 

    That is an interesting thought.  You could filter your table against a second table but I suspect that it will take quite a bit of time for that.  As far as doing it all in Excel, as long as you have a Backup of your table, you can always bring it back in. with a data flow.
