Hello dear colleagues.
The question is as follows: there is a multiproject in PCS7 v8.0 system. When loading changes to OS project the "Picture Tree" checkbox was checked. Names in Picture Tree were pulled from OS Area IDs from AS project. What is the correct procedure to restore custom Picture Tree Names?

I think the only way is to manually rebuild it by referring to retrieve of an old archive with the picture tree the way you want it.  Or you can attempt to adjust your project hierarchy so the compilation gives you the correct result instead of using manual picture tree.

Export/Import functionality doesn't exist in PCS7/WinCC picture tree manager until after PCS7 v8.1 (either 8.2 or 9.0, I can't remember 100% for sure).

Thanks you for your reply.
