"Record for update was not found by its SysRowId"

As you can see, I’m getting this error on alot of my DMTs. I’ve deleted the SysRow column all together, and I’m still getting the error! Can ssomeone please tell me what this is, and maybe how to avoid it in the futre.

Looks like your dmt data has a sysrowid of all zeroes which it can’t find
Remove that column from your dmt template

If you look at the far right , you’ll see that I’ve already removed the column. That’s why this is not computing in my brain.

What columns are in the DMT?
It will require:
Company
Key1
Key2
Key3
Key4
Key5
ChildKey1
ChildKey2
ChildKey3
ChildKey4
ChildKey5

I have those columns. I only deleted the last 2 columns.

Are you only adding? Maybe remove the Update flag?

I thought about that also, but I do have records that need to be updated.

Could you verify there are no BPMs and also send the complete list of columns from your CSV file?

I cannot remember the specifics, but when preparing to go live, I remember an instance of having to do additions first and then updates in two separate DMT runs.
