I would like to calculate the following figure in a accumulative monthly amount.
For example, how do I compute the value of the Cumulative figure (highlighted in red) for "Maint Plans Created" & "Maint Plans Scheduled" for each month starting from Feb based on the excel formulat in column G. Thanks.
I believe the source data is coming from Excel. You need to format the table into tabular mode in Edit Query, In power query create a date table ( there's many post on how to create date table in PBI) and then create a quick measure on the table and select running total , base value will be your maint plans created, field value will be your date. it will calculate the cummulative value.
