Hi Henning
Not answering your (new) question - but using the flag "4" for save(..) does not work for you? Do you need to have a dynamic limit?
Flag 0x04 on save for 'replace' existing contact address does work, if I want to allow exactly 1 contact.
But what if I want to allow max 3 contacts for a specific customer and max 5 contacts for another one?
Mit freundlichen Grüssen
