I am sure I am missing something very straightforward, so some assistance would be appreciated. In my load script I load a master calendar, Which has a range of dates corresponding to the range of dates in the transaction file, plus the number of the week in the year. The date links to a date field in the transaction file I am loading. I want the user to enter a date (any date in the range of the master calendar) which I store in a variable I called 'vInputDate'. Based on the date the user enters I want to assign a variable the corresponding value of the week variable.
So if the user enters 12/12/2020, I want the week variable to reflect 50, and if the user enters 16/12/2020 I want the week variable to reflect 51. This needs to be done dynamically as the user can select whichever date he wants to report on.
