Q: How can I avoid that all connectors or inner parts of the planning are displayed, although I displayed only one article isolated.
A: That only happens if you switch in the Visu Manager connectors/ internal parts to invisible before isolating the article. If you turn on later the visibility of connectors/ internal parts, the described effect is caused .
To avoid this effect, use the following procedure :Isolate the article when connectors/ internal parts are (still) visible. Turn off the visibility of connectors/ internal parts just when the article is already isolated. If switch on the connectors/ internal parts now, only the connectors/ internal parts of the isolated article are displayed.
