Discrete Job operations not updated

Hi,

We are experiencing a problem when, from the application, updating an Unreleased Discrete Job, from the Primary to an Alternate routing.

We don't get any message or warning, but the operations are not updated.

If I insert the necessary details in the WIP_JOB_SCHEDULE_INTERFACE and run the WIP Mass Load, the updates are correctly performed.

Are you aware of any setup to look at?

It worked fine until last month.

Thanks in advance.

Cyrille.
