Formula to expand a record across a date range

Gurus,

I have a client that wants to create a "date based report" based on a record that includes a date and duration.

For instance, Record 1 - would include a date 7/11/2015 and a duration of "3 days".  

They want to see a report like this:

Group: 7/10/2015
(Detail) *No records*

Group: 7/11/2015
(Detail) Record 1

Group: 7/12/2015
(Detail) Record 1

Group: 7/13/2015
(Detail) Record 1

Group: 7/14/2015
(Detail) *No Records*


Each time "Record 1" is listed it would include other fields from Record 1, I'm just keeping it simple for display purposes.  Also, there could be other records that would be listed within each "date".

Any way this can be done?

Thanks in advance!

How far into the future/past?

How long a date range?

Create a Calendar table with one record per date.  Add that table to your report.

Use a record selection formula (or a join if your DBMS supports that type of join) that restricts the joined records to Calendar date >= transaction date and Calendar date <= transaction date transaction date + duration.
Group on Calendar date.

mlmcc, I was hoping the date range could be added as a date parameter.  It normally would be printed for a week or so at a time but the date range would change.

IdoMillet, I can't add any tables to the database.


The application is for a "Project Record" which has a start date, number of days, number of workers.

They want to create a report that would show each date, the job names for that day, and the number of workers required.  However, if a job spans more than one day they need to also include that job and the number of workers on that day (group) as well.

Any thoughts appreciated!

Thanks

Here is one method.

It uses several formulas to build the lists and display them

mlmcc,

Wow - super impressive!

I'm on vacation for a few weeks so I'll have to roll up my sleeves to get it to work with my data set but it looks perfect.

Thanks so much!
