I have transaction looks like above picture and would like to sum up and display as below picture.
How to do that?
Thank you @Darren_Murphy . It works. Anyway, it missed the third step to add lookup value from that relation.
Anyway, I still don’t get the idea why to create a multiple relation to match itself?
What would you want a Lookup for?
A lookup will only give you the associated value with the first of each set, which I assumed is not what you want?
Matching each set to itself allows the rollups to give the correct result.
Edit: Actually, the result of a lookup would depend on whether the relation is single or multiple. A lookup through a single relation would give you the first value, a lookup through a multiple relation would give you an array of all values. Either way, it’s not what you need.
Relation cannot roll up number. Hence, I have to use lookup after relation every time. Is it right? I am not sure.
Dear @Darren_Murphy ,
The solution you advice me works very well. Thank you so much.
I face a new problem. After display on the table, some records are have the same matched item as in attached picture. How to screen them out?
Use that if-then-else column as a filter - “where if-then-else is checked”
Thank you. It works.
![]()
