Hello,
Please clarify what you mean by copy, did you copy the script (text) from one open client session to another or did you use back up and restore to copy the environment or any other method.
I recommend checking if this is a client or server side problem. You can verify this either by opening the logic on a different client machine or by checking the logic directly on the server using UJFS.
If this has occurred on the server level I recommend just rewriting the content, through BPC web client, validate and save again and check if that fixes the problem or if the problem occurs again.
Best Regards,
Leila Lappin
