When retrieving a project from PCS7 V9.1 SP2 UC01 Simatic Manager results in error code 3020:66. 

"When merging the projects and the libraries into <Project name>, it is possible that some could not be added to the multiproject”.

The result is a project with no sub projects or tree structure. 

Anyone have any ideas?

Hello,

Is there anyone solve this issue? I also met but the version is PCS7 V9.1SP2UC03.

Thank you.

Hi Jimbob,
I had the same problem, but with UC03. I solved it by reinstalling the licenses. I recommend checking their status in ALM. I saw that they were corrupted. After reinstalling the licenses, the retrive completed without errors. I hope help this helps.

Regars.
