Hi there all,
I have a question about a DAX formula. Probably very simple but I can't figure it out.
I have a data set with financial data. Every line in my dataset stands for 1 payment. The data concerns declarations of care provided.
The 'Dat_Begin' field shows the date on which the performance was delivered. This date differs from the date on which payment was made. This is because healthcare is often claimed with retroactive effect.
Well I would like to make a graph with the development of costs. However, because the care is billed retroactively, I do not want to show the last 3 months (for example, dat_begin) in the graph. This is because otherwise the graph always expires enormously at the end of the period. This therefore gives a distorted picture. After 3 months, most declarations are received.
What do I want:
I want to make a formula that goes back 3 months from the last day of the previous month.
Example: today is 30-09-2019, so I want the date 31-05-2019 to be returned.
If I look again tomorrow (1-10-2019), then the formula should return 30-06-2019. Also on, for example, 15-10-2019 the formula must still return 30-06-2019.
Who can help me? Thank you very much in advance!
