Hey,
I have slight problem with the formula field: when I use the sum() function over a filter, the effect of the filter disappears.
For example:
filter(lookup('OWF in Portfolio', 'Capacity [MW]'), lookup('OWF in Portfolio', 'Status') != 'Stopped')
works fine but when I sum over it, the effect of the filter disappears:
sum(filter(lookup('OWF in Portfolio', 'Capacity [MW]'), lookup('OWF in Portfolio', 'Status') != 'Stopped'))
Has anyone an idea of what the problem could be ?
Thank you very much.
Hey @arnperr, we’re already looking into this issue, as another member reported a similar problem a few days ago: Aggregation formulas ignore filter inside (#2666) · Issues · Baserow / baserow · GitLab
While we are investigating the issue, you can use this workaround:
- Create an additional field in the looked-up table with a formula such as:
if($condition, field('a'), 0)
- In the final table, sum this new formula field that already contains the filtered values
Apologies for the inconvenience! 
Hey @arnperr,
just a heads-up that a fix for this bug is in the review phase and will be part of the next release: Resolve "Aggregation formulas ignore filter inside" (!2459) · Merge requests · Baserow / baserow · GitLab
Thanks for your feedback
