Report Writing / Programming in Express Maintenance Part 1
I have found calculations and accessing variables not intuitive in the RAP environment so these are my notes to help eliminate some pain between tasks.
Basics: SQL = "Structured Query Langauge" Variable = "A container to hold a specific value, this could be an integer, string, etc.."
Start with the end in mind
- Add your local variables these will be containers for values, see image above
- Declare your global variables where values will come from another source
- Map your global variable to your local variables
- Sub reports will have logic and calculations then will get assigned to your global variables
