Access custom meta data from another topic

I would like to access the custom meta data added to a topic in a different topic. Is that possible and how?

As an example, I would like to add a list of entries that are not charged with their total money to be billed to the TimeTracker app main topic. From my understanding I would add a %SEARCH% or %DBQUERY% that finds all entries that are not charged. For each of these I would like to acces the stored hours and calculate the amount to be billed. With nested queries I would calculate the total amount per entry. Is that a good way to do that?

So, how can I iterate over all custum meta data of a topic?

Have a look at RENDERMETADATA or the native QUERY macro.

Thanks for the quick reply. I didn't realize that RENDERMETADATA can be used to produce a comma separated list.
