[SOLVED] Attribute Type Numbers

Hello,

I have script in ARIS 7.x for import/export objects and their attributes. This script uses "Type number" to identify attributes of the object, since they are User-defined and have no API name.

I thought this type number is permanent, but I was proved wrong several times. Why is this number changing, despite the fact I did not update ARIS? Could it be caused by changes made in the filter?

Any help will be much appreciated.
