Posted on by Dynamics_User07 125

I want to get deleted row fields  with power automate but it seems its not possible unless we use plugin.

I have a child entity (lets say project) on parent entity (lets say Store) . I want to update the field on parent entity( field name is projectexits) to NO when no child record is assoicated with parent entity or every child entity is deleted 

I know it can be achieved with plugin preimage as I am new to dynamics , Can you please share me apporach for it ? Please let me know if otherway is also possible , I tied using Calculated filed but its not possible on 1:N relationship

    Hi,

    Have you tried creating rollup field to store the count of project records?

    learn.microsoft.com/.../define-rollup-fields

    Now use Business rule to set your custom field is Project exist to yes when count >0 else set No

    Hi Bipin,

    Thanks for ur suggestion we cannot use roll up field for some reason so we need to use the plugin only, any suggestion or sample code

    Hi,

    Check below article for delete plugin prevalidation stage

    You can write something similar to that and check the count of project record excluding the current record then update your field on parent entity
