Beast mode - Join data from another line

Hi Domo community,
I would like to achieve a join from a single dataset.
Here is the column I have :
ID, Parent_ID, Parents_status, Comment 11 21 2 12 21 3 21 Done 1
I would like to do some beast mode to join data between lines and create two type of data:
Extract the parents status to apply it to the ID in the column Parent_status_New
And the child comment_sum which sum the number of comments attached
ID, Parent_ID, Parents_status, Comment, Parent_status_New, Child_comment_sum 11 21 2 Done 12 21 3 Done 21 Done 1 5
How should I create those beast mode? Do you have any idea how to do that?
Many thanks,
Julien

HI @user047019
You won't be able to do it in a beast mode but you'll need to use a Magic ETL. You can have your original input dataset and then filter through two filter tiles. One filtering where
Parent_ID
is not null (children) and the other whereParent_ID
is null (parents). Then you can use a join based on the children'sParent_ID
with the parent'sID
field. to get theParent_status_New
field. In addition you can take the output from your children filter into a group by and group by theParent_ID
field and count theID
field to get theChild_comment_sum
field. Us a join to join this back to your parent data based onParent_ID
(which you group by) to theID
field from the parent filter.**Was this post helpful? Click Agree or Like below**
