I have a table as below and try to find solution for a matching problem. I would like to get the same value in [Value] for each month in [Date], if [Date] in the year 2019. This mean, all rows with [Date] = 01.01.2019 will get [Value] = 100, and all rows with [Date] = 01.02.2019 will get [Value] = 250, and so on. [Date] of 2018 will stay in the data.
My initial approaches are LOOKUPVALUE(), and CALCULATE() together with ALLEXCEPT(). However they don't work.
