I have a column name - ‘Monthnum’ and the values in it are arranged like:
and so on
On a monthly basis I have to change the filters to run the filter on the previous month. So for example if I have to run the report in the month of June 2020 , the filter I have to select or the value in the filter is 202005
Could you please advise how can I put this into a formula or parameter to ‘automatically’ take month number as that of previous month with the format of monthnum column? ?
