when running job scheduling AX creates various jobs depending on the route. Each job is linked to the next one by Link (Start/Start, End/Start, etc) and link type (Hard/Soft) .In the Route version I can setup the link type. How can I set up the link (start/start, end/Start, etc)? Do I have any influence on that?

Thanks!

Hi Joe,

You can do that by route Next parameter and create a network. In addition, you have to check in the Production parameters Route Networks checkbox.

For example, if you have two operations that need to be finished before a third one to start, you will have the following:

No | Name | Next

10 | Oper 1 | 30

20 | Oper 1 | 30

30 | Oper 1 | 0

Hi K.II!

Thanks very much for your reply. I have been aware of that before. My question goes a level deeper as job scheduling sets some links between jobs (found that in the Class entry). I wanted to know if yi can influence that setting.

 

Thanks anyway! Highly appreciated!

Well, you can set a link type - hard or soft. Hard would allow capacity to schedule in a way that there will be no time space between the operations, while soft would allow for some time space between operations (for example awaiting for another operation to finish in order a simultaneous operation to start)

I have that set up. unfortuantely my environment doesnt allow me to post any screen shots here, but if you follow the path Production/Production order --> Select a  job scheduled production order. Click on All Jobs in the Top Panel and then choose the General Tab. There is a section call Job showing the following information:

Job Type (Setup/Process/ etc)

Link (end/Start, Start/Start, etc) --> I ask my self how I can influence this setting.

Link Type (Hard/Soft)

The End/Start would be where you have subsequent operations, Start/Sart would be where you have a primary and secondary routing step. This does relate to the link type, job type and the route setup.

Why do you want to influence this setting?

Basically depending upon the routing setup the system knows what this should be set to and therefore sets it. Any changes to this from what the system would expect would only cause you potential issues.

Primary/seconduary Operations are extactly I have any issue with. I thought -as you wrote - that this should be a Start/Start link between Primary and Secondary. If I look at the job list my primary (process) job has a link end/start. The secondary (process) job as no link.

Primary and secondary operations are exactly the issue I ahve with. My primary process job shows me a end/start link and my secondary has no link at all. Operations have a link type "Hard" in the Route. I thought - as you wrote - that the link between Prim & Sec Ops shoudl be Start/Start

Let me set something up, the hard link should set this to "Complete".

I believe that because the operation is not primary, the times from the primary operation are used to schedule the secondary operation. This means that the times do not have to be specified for secondary operations. Therefore it would make sense for none of the job links to be created for the secondary operations because all timings and scjheduling is driven by the primary. Kind of makes sense, basically the system does not need to set the field, because it does not use it, but it depends what you are trying to achieve with the field.
