Hi Victor,
Sorry for the delayed response. 

The ASSIGN rules is only intended to affect the data that the user sees(the active/current event). This usually means that you can create helper fields, but they rely on the basis for your calculations being in the same event, or in previously registered data. The behavior you describe in 2.25 was not planned, and can be seen as a bug. 

There is two alternative options that can be pursued:
- Try creating a program indicator with analytics type "Enrollment"(introduced in 2.26). This will allow you to compare data from the latest event in each program stage across entire enrollments. Possibly this can take away the need for the helper fields.
- Make a helper field in second program stage, and make an assign rule that assigns "the other way". You will be able to query data from all other program stages when calculating and assigning values to helper fields.

Best regards,
Markus

Since currently it is not possible to do this kind of analysis in Event Report, we have created some ASSIGN program rules to copy values from closure stage to opening stage so that we have all the information we need for analysis in the same stage.
