Can anyone please tell me how to fix this or what I am doing wrong?

Please help.

Hello,

I was unable to replicate the issue. Production Order worked fine in my case. Can you please give me some more details on what values you entered. Especially the Working Hours section in the Workstation associated with the Production Order Operation.

I fixed it. The issue was the working hours on all the workstations were set to start at 00:00:00. When I changed it to 00:00:01 it worked and went through. This might be a bug that is worth fixing though.

Tried the same with all workstations set to 00:00:00 yet could not replicate.
system gives you error stating break down the operation into multiple operations which is an expected behaviour.

Do let us know if it gives you an error again.
