Hello,

is it possible to set priority to TransportPoint ?

I need to prioritize the TransportPoint between them.
Some place have to be deliver before other.
I already use the product priority whose purpose is different.

Thank you

I believe what you are looking for is the toursection attribute. From the documentation:

Position of the transport point in a tour (0 <= tourSection <= 1000). Within a tour the tourSection values != 0 of the transport points will be sorted ascending so that it is possible to pre-order the transport points. Transport points with tourSection 0 will be placed anywhere. TourSection 1 will be the first stop within a tour, and 1000 will be the last stop. There will be not more than one transport points within a tour with tourSection 1 or 1000, respectively.

General remark: with in xTour priority does nothing with the order points are inserted into a tour. Priority only raises the chance an order will be planned in, it has no effect where in the plan is will end up.

When I use tourSection with transportAB I have the following message.

Could not plan basic tours (Reason: Could not set partner relation). Engine error: Invalid partner stop tour position (code: -1063) in transport order 2000.

How I have to fill tourSection ? How it works exactly ?


Thank you

In case of an AB order, transportpointA.toursection should be smaller or equal to transportpointB.toursection. I'm not sure how a value of 0 is allowed for only one of them since 0 is special value for anywhere. I'll check this further.

0 values are allowed and do not violate the a.toursection <= b.toursection rule. B.toursection should be greater then 1 since 1 means "has to be at the begin of the tour" which does not leave room for A to be inserted before.

Examples:
A.toursection = 0, B.toursection = 0 => valid
A.toursection = 0, B.toursection = 5 => valid
A.toursection = 5, B.toursection = 0 => valid
A.toursection = 5, B.toursection = 5 => valid
A.toursection = 8, B.toursection = 5 => invalid
A.toursection = 0, B.toursection = 1 => invalid

very clear.

Thank you

Hello Michele,Joost,

@Joost: thanks for the detailed comments.
@Michele: be aware that the tour section handling as described by Joost is easy to use within a planning of a single tour.
But: it could get challenging if you want to dispatch various AB-Orders over a set of vehicles and you still want to ensure some kind of internal sequences. Maybe it is a good idea to get in touch with Clement to check this usecase in detail.

Of course Joosts hints are great to know but sometimes a full picture of the "requirement" gives us important info for an optimal paramneter set.

Best regards,
Bernd
