External Lists - Limits

What are the limits for External lists
how many items are allowed?
is there a hierarchal or reference limit?
Is there a performance issue for large lists?

TIA

Dear David,

There are no limits related to the elements.
However the amount of level labels and references is limited:

  1. Lebel label: up to 9

  2. Reference: up to 49

Any performance issue would be related to the list itself, quite hard to tell in advance.

I hope this answers your questions.

Have a nice day.

Kurt
