Create new records based on data and system date values

[klikgevoel]

Assume the following dataset

Set NullInterpret = '';

Let vCurrentDate = Num(Date(Today()));

Data:

Load * Inline [

Id,StartDate,EndDate

1, 01-01-2019,

2, 25-01-2020, 27-08-2020

3, 01-01-2020,

];

What I try to achieve is creating a new "monthly" record for each record untill an EndDate is hit. So ID 2 will have 8 repeats, while ID 1 and 3 continue till vCurrentDate.

The final result will look like this:

ID	YearCounter	MonthCounter	StartDate	EndDate
1	1	1	01-01-2019
1	1	2
1	1	3
1	...	...
1	2	20
2	2	13	25-01-2020
2	2	14
2	2	15
2	2	16
2	2	17
2	2	18
2	2	19
2	2	20		27-08-2020
3	2	13	01-01-2020
3	...	...

What you need is an Intervalmatch function.
