How to persist values in BIRT?

Manuel Felipe Amaya (1321427) | asked Aug 09 '16, 10:05 a.m.

I need help saving a value from a row and comparing it with the next row.

For example, the report has to show how much time a WI was in a state. (Right now I have how much time a WI was between every save, but I can't persist the first timestamp in order to compare it with the next).

 A BIRT report has an initialization script that runs before anything else. You can declare global variables

Beware, though, as the charting API doesn't see those globals - you have to explicitly share those values in order to use them in a chart context.
