● I_STEP = 1
Call is made directly before variable entry.
● I_STEP = 2
Call is made directly after variable entry. This step is only executed if the same variable is not input-ready and could not be filled for I_STEP = 1.
● I_STEP = 3
In this call, you can check the values of the variables. When an exception (RAISE) is triggered, the variable screen appears again. I_STEP = 2 is then also called again.
● I_STEP = 0
The enhancement is not called from the variable screen. The call can originate from the authorization check or from the monitor.
