AutoCAD Inventor :: Change Browser Name To Part Number

I need to make installation plans on climate ceilings, which are steel cassettes with Meandro tube element located where cold or hot water is flowing through.

[URL]......

Now it may occur that a cassette is given a code 700 which represents the type of cassette. If inside the cassette is placed a Meandro element its  become a follow number eg 700-01.

It may also be that the same cassette No. 700 gets  another Meandro element  and because the cassette has not changed shape the number 700 remains the same but the follow number change e.g. 700-02.

At the moment I change the number in the browser,(inv2012) I therefore want  automatically the  iproperties ,partnumber and stock number, to fit. When I go to the BOM, the part- and stock numbers automatically will be placed.

The browser codes are not displayed in the BOM. So if I specify for change I only have to do so in the browser. I wanted to do so by iLogic but then ran into problems. I found a tutorial from Rob Cohee with ilogic so you won’t forget to fill in your iproperties.

I also wanted to do so with the iproprtie Stock number but get an error stating that I must declare the name. How must i declare a name.

Also i was told for entering the browse name in ilogic i had to use  displayName, but I get a error stating that the name is Read Only.

So how can i, after i change the browse name, automatically  fill in the iproperties ‘part number and/or stock number? Is there an ilogic code for?
