SQL Insert into UD Table view

Hi,
I have a question please.
If we manage primary key by BPM, what should we put in Key1 (in the DMT Template) ?. I just posted a post against this, I was wondering if you had any answers ?
I increment Key1 in a BPM, in GetaNewUD10 more exactly, but when I upload my file to DMT, I don’t know what to put in key1 to trigger my BPM.

Here is my topic if you want answer me there since this one i old or maybe solved.

ADD RECORDS IN UD TABLE WITH DMT

Thank you
