Condition exclusion D only if group 1 active

Hello all!

We have the requirement to set a certain rebate condition (YNR1) inactive if a certain basis price (ZVXX) exists.

So i set up the condition exclusion adding the conditions to exclusion groups:

Y003 - YNR1 and Y004 - ZVXX

and then made an exclusion "D" for the two groups. (D - Y004 - Y003)

This works fine until the condition ZVXX is set inactive, because of some other rule.

The exclusion still works, obviously it only checks if a condition of "group 1" exists to set the condition of "group 2" inactive!?

What i would like to achieve is an exclusion as described above only if the condition of group 1 (Y004) is active (green).

Thanks in advance
