How to get the job seq and its dependencies from OPC sched.

We have been looking for some tool which will create a job flow diagram or Job sequence with dependency from OPC scheduler.
There is a tool to create job flow diagram is available for CA7 but we are not sure on the OPC how it will works as it's deals with Application Id's
and each of the application will run multiple jobs and those jobs will be dependent on multiple other application jobs.

Or Any option in OPC scheduler to find out the job run sequences for particular day run as an whole.

It would be really helpful if you could share the tool or the source library of OPC where we can find the job sequence.

Kindly, let us know if you have any information on this.

Thanks in advance.

I seem to remember from back int he day (late 80s) that there was an option built into OPC (TWS now) which would do this and display on screen. I doubt that it has gone away so it is a case of looking through the menus, help and manuals.

Or waiting for "Blackthorn" to come to your aid (except he may only visit the Beginners' Forum).

No, I lurk around here as well (under my real name), although didn't realise I was the forum's TWS expert! Unfortunately I haven't worked with TWS for about three years now, so my memory is starting to get a little hazy and I don't have a system to check things out on.

So, there is indeed an inbuilt option in TWS. You can just type the GRAPH command from within an application to display a graphical representation of that application's jobs. However, there are a few drawbacks to this. It only relates to jobs in that application; not dependencies in to other applications; it does not take account of when they will run or if there are multiple runs of that application scheduled; you need GDDM installed; and for any more than about 10 jobs the resulting boxes are so small as to be unreadable.

What you really need is an off platform flowcharting package and there are several available for TWS. The two that immediately spring to mind are TWS/Graph or Visual Job from APS. Beta Systems used to do one as well although from a cursory glance of their website I can't see it now. There was at one time some freeware available from IBM as well, but I've never used that and don't recall what it was called. From what I've seen of it I think it was a bit clunky compared to the other two.

I'm not aware of anything within TWS that will give you what you want, even in a non-graphical format. The closest would be some of the reports that come out of the daily planning process (bear in mind numerous reports are available but may not all be produced, depending on the parameters you have set in your daily planning job).
