is there any possibility to sum values of different fields from different pivot-tables?
I would like to sum two values from two tables for further calculation.
Each of the two fields of the different tables is a calculated value.
The fields I want to sum are:
"Qualitätspunkte Therapieanzahl" from table "Therapieanzahl" and "Qualitätspunkte Therapieklassen" from table "Verteilung Therapieklassen" and then devide the sum by 2 for each ID and for the average of all IDs.
