Error with CPTK transaction

Hi,

We are upgrading from 6.0 EHP4 to EHP6

When we execute CPTK transaction with the project number P/D83/22/000298, the transaction produce the following error: WBS element does not exit for all the WBS element belonging to the project.

In the image above you can see the error, the WBS element correct number is displayed with green traffic light and the internal number corresponding to the same wbs element is displayed in red traffic light.

We have checked that all the WBS element exist for this project. Can anybody help us?.

Thanks in advance.
