Create row(s) according to values into different columns

[crixo]

I'm trying to "denormalize" data from Exchange calendar. Dataset is a list of appointments from outlook calendar mixing recursive and single appointment.
Recursive appointments are single entries with recurrency details within a dedicated column, as record, named Recurrence.
I need to create a row for each occurence of the recursive appointment leveraging on the data within the Recurrence. (eg. if the appointment occurs 50 times, I need to create 50 rows. If the appointment occurs every monday for 5 months, I need to create ~20 rows).
The logic has to be executed only if the value into a given cell matches a given condition, basically if the appointment is recursive or not.

I'm a newbie w/ M/power by, I would also appreciate hints/tutorials on finding solutions rather than the solution itself.

Hi @crixo 

When filtering the Recurrence, it also has many records.

Do you mean you want to expand all the content of it based on the happened times?  If you expanded it, it will return muitiple rows.

Hi @Anonymous,

Yes, I need to duplicate each row that is an appointment with the Recurrence data.
For ex. if I dectected, according to Recurrence.HasEnd not null, that an appointment/row has Recurrence.NumberOfOccurrences = 20, I will duplicate that row Recurrence.NumberOfOccurrences-1 where 1 is the row itself.
I need to duplicate the row to count each physical occurence after groupping by its category.

I hope that helps to clarify the scenario. Thanks a lot for your support
