simple solution, but not much as to why
the FIND will find the 200 objects, great!
instead of doing a CREATE in the next rule,
CALL A 2nd PROCESS -- this will pass the context of the 200 found Objects to that Process, so specify Abonnement as INPUT
This 2nd Process will "CREATE WITH" on each of the passed in Objects -- no IN BATCHES OF will be required.
TIP: If you turn on Logging (from the control panel window), you will see the Object IDs get passed in, and the loop through those objects.
Logging scrolls very fast sometimes, so if you want to learn and see more in-depth, add "TAKE BEST 3" to the Query and then you should see the entire process easily in the log.
This is much faster than using IN BATCHES OF 1, which will work, and will allow you to only have 1 Process, but its slower.
1st process: Create_Subscriptions
2nd process: Create_Subscriptions_b
this way they stay close together in the Elements tree
