Watch out for your batch license

The function VISULIC shows you your current X3 license. There is a line in that screen that shows the number of possible simultaneously executing batch processes:

In the above case, it says 5. But the real number is less than that. You have one slot always occupied by the batch server itself and one more by the accounting tasks - that leaves you with 3.

If you are planning to have a lot of custom developments in your X3 solution, you want to ask how many simultaneously executing batch processes your license will allow. If the number is too low, it might prove to be a limiting factor at some point.
