In order to obtain a single ppt report with different slides, one for each value of a specific field, you have to use the the page feature inside the template editor instead of the report cycle functionality.
With the page feature you can:
- create a different slide for each value of a field
- create a different slide for each combination of multiple fields (e.g. using a tablebox)
- create a different set of slides for each single value of a field or for each combination of multiple fields
hope this helps.
