Thank you Matthias but I am struggling to understand this one - sorry! Could you give a little more detail to explain what you mean?
see attached picture. Instead of ID 52 and ID 12 it would be better to have an own ID defined in an own column left to the Name column in the parts tab. That prevents me from having double-IDs.
It would be nice to assign an own part ID to each part. At the moment the nesting Report assigns numbers from 1 to … For that you need to implement a new ID-column in the parts tab. It is a little bit like the name-column in the sheet tab. In my jobs I write down the number of the sheet there.
