Hello,
I asked a question earlier about this issue. I will try to rephrase my question.
I have a dataset that have three variables: period (datevar.), sales and depart. The time series starts in 2021-01-01 and grows every month when a new month’s sales figures is added. The data for the latest months (in this example 2022-02-01 and 2022-03-01) is not reliable.
For now, I am using a macro that I must update every month. With the macro I select the starting date and the end date (current date minus two months.)
I would like to create a macro, with TODAY Function or something else, so I can automatically select starting date (2021-01-01) and end date (current date minus two months: 2021-01-01). I would like to achieve this without needing to update the macro every month.
