Auto associate ECAD Schematic & ECAD Board

Hello,

I try to auto associate the ECAD Schematic & Board in Ecad Neutral WGM.

We use the non separable generic ECAD Design.

From the generated files ECAD generic, ECAD Schematic and ECAD Board, we use the Schematic as Board Files for structure purposes.

The ECAD schematic should have a owner Link to a WTPart. This WTPart has also the BOM

The ECAD board should habe a owner link to a WTPart.

After the first advanced Check-in we want to auto generate the Parts for Schematic and Board.

How can i do that?

If I try to auto associate the two files then i get a error message.

I think I need to change a Preference but i can't find it. Can someone help please?

greetings

Marcos
