I'm not sure this question has already been talked about or even solved as i could not find anything on the forum. My title formulation might not be the best so i'll try to explain it :
I use dolibarr and i would like to make some data analysis with its database. I made a question that sums every invoice line for a certain product category and returns an amount, aggregated by month based on facturation date. This works like a charm :
Problem is i want to display a big number that dynamically shows the total amount for a period of time set by a dashboard filter. For example if i select a time span of february '21 to april '21 it should display 3161,95 (577.66+1720.65+863.64) but i only ever get the first value of this time span : 577.66.
