Power FX Formula column in Dataverse: Calculate sum of Power FX column in related entity

(1) ShareShare
ReportReport
Posted on by 12

Hello everyone,

I want to use a Power FX field to calculate the SUM of a column which is located in another table/ entity.

 

The logical/ schema name of this related entity is called "mca_machinecheck", the display name is called "Machine Check Item".

 

The column itself of which I would like to calculate the sum has the external/ schema name: mca_accomodationcosts and the display name is called  mca_accomodationcosts

 

This column is also a Power FX formula: 

'Overnight Stays in Days' * 'Machine Check List'.'Accomodation Costs'
 
This has worked to access an attribute in the Machine Check List table but the other way around it does not seem to work unfortuantely with the Entityname.Columnname notation.
 
Maybe a rollup field is also an opportunity but I do not receive any useful recommendations when I select the correct related entity.
 
Thank you in advance and kind regards
Tobias

    Powrfx column Roll-up logic is not yet supported. It will be preview as a new feature in Jan 2024.

     

    Update on 19/03/2024: power fx roll up feature is now removed from the release plan and on hold indefinitely.

    @Stevieed  is correct.

     

    More specifically, it is planned for preview in Jan '24 and GA in March '24:

    Anyone know if the "use power fx to define column level rollup logic" feature has been quietly shelved? It no longer appears on the 2023 wave 2 or 2024 wave 1 release plan pages.

    Correct it's no longer planned.
