I have a CSV with various fields, including
Internal ID and
Phone. I want to match
Internal ID to
Contact ID, and add
Phone to the set of phone numbers for each contact.
I use a simple field mapping for import, shown here (real data redacted for most fields):
But I get the following error:
When selecting the field mapping, there are 5 options with an asterisk
* by them, and
Contact ID is one of them (along with the other 4
External Identifier), indicating (I presume) that they're valid for matching to a contact. Why is this not respected when actually doing the import?
And why does the preview say there are 459 "valid rows", when it should already know at this stage that it's not going to succeed?
I'm wondering if I need to create another dedupe rule for
Contact ID, maybe? Or if I'm matching on
Contact ID, maybe I don't need dedupe checking (set to "No Duplicate Checking"), is it a special case, maybe?
Any help is appreciated, thanks.
