Hi,

we have updated our System to the 7.4.1 and since that we have problems. We are not able to shift a Schedule before it was possible.

The Workpackage was created with the 10.12.2018 (1.png)
I will change the date of beginning to the 10.19.2018 (2.png)
after a few seconds i got an error (3.png)

Is this a known bug?

Best regards,

Andi

Do I have to open a workpackage here?
