Overview
There is a setting that can be toggled which will hide or minimise the visibility (with a lighter colour) of out of flow skip jobs based on the last job by planned/scheduled date.
An example of "Out of Sequence" would be creating a Delivery job when the last job is an Exchange, or creating an Exchange job when a Delivery has not yet been created.
Setting
The setting in question is called "Job Creation Type Checks" and can be found by:
Hovering over Administration and clicking Settings
Click on Skips & RoRo
By default, this is enabled.
Behaviour & Appearance
With the Setting Enabled (Default Behaviour)
If the setting is enabled then "out of sequence" buttons will be visually reduced. For example if a Delivery job has been created the buttons will appear as below (the "Delivery" button is white, but the jobs that depend on the skip being "off site" are not.)
Similarly, if a Collection job has been created then the buttons for jobs that depend on the skip being On-Site are white.
Note: Although the buttons are minimised they can still be used to insert a new job between existing work.
Finally, if you attempt to create a job that does not fit in the flow of planned and completed work (like creating a second collection job when the previous job is also a collection) you will get the below error message on the job creation screen and cannot continue.
With the Setting Disabled
If the setting is disabled then the out of flow job buttons are completely hidden and cannot be used at all.
In the below example a Collection job has been created, therefore all the "On-site" job types are hidden.
"Non-Standard" Job Types
Some job type buttons are not enabled by default on new systems or can be disabled and will need adjusting via their own settings before they will appear at all (at which point they will become subject to the above rules).
