Problem in route determination
In customizing, under route determination -> "Departure country zone and destination country zone", I am not able to make new entries. When I enter the screen initially, there are no values found and it is greyed out, and after clicking new entries, it lists out about 20 values, I do not know from where it actually picks up the values (Note: Initially when i entered the screen, there was no values found) and in the bottom of the screen, it shows that 0 of entry 0 chosen (it is the screen which has 20 values). I am not able to click or highlight any of those values.
Kindly let me know what would be the problem.
