Merging a dataset

When the work on a dataset is taken as finished, we can merge it, in order to display the completion of the manipulations on lines and the periods it contains.

...

To merge a dataset, simply move it to the "Selected datasets" tab and press the " Submit" button.

...

Modifying a part of the existing offer

In the life cycle of a transport offer, it can happen to modify the offer on a part of the existing offer only on specific lines.

...

Now that the modifications are done, it is necessary to merge the data set "Copy_New" so that the new data are taken into account in the offer.

...

Extend the offer

Another possible need is to extend the offer on one or more lines. The following diagram represents the objective we want to produce in Chouette :

...

Now that the modifications have been made, it remains to merge the "Copy_New" data set so that the new data on the "City" line are taken into account in the offer.

...

Remove the offer of a line

Your objective can also be to remove the offer of one or more lines from the merge offer. The following diagram represents the objective we want to produce in Chouette :

...

For example, the data on the "City" line must be removed from the merged offer.

...

To empty the data on the "City" line from the offer, create a new dataset, select the period for which you want to empty the data, choose the "City" line from the list and press " Submit".

...

The dataset is created and no longer contains data on the line for the set period.

Now merge the created dataset so that the old data on the "City" line for the defined period are rewritten in the offer.

...

Modify a route on a line

Another possible use case is to modify a route on a line in a merged offer. The following diagram represents the objective we want to produce in Chouette :

...

For example, we need to modify a route on the "City" line.

...

The "New" dataset that contained this line is in "Archived" status, so it must be cloned in order to make the desired changes to its copy.

...

Once the copy has been created, click on the "Edit this data set" button.

...

In the form you must leave only the line containing the route to be modified, in this case you keep the line "City" and submit.

...

After the validation of the changes in the dataset form, click on the name of the line to display the routes it contains.

...

Click on the name of the route and click on the "Edit this route" button.

...

On the editing page you can remove or add one or more stop areas and submit.

...

Now that the modifications have been made, the "Copy_New" dataset must be merged so that the new data on the "City" line route are taken into account in the offer.

...

Rollback on an old merged offer

To undo the merged offer, there is a Rollback function available in the list of actions on previous merges. Simply click on the gearwheel of one of the previous merged offers and click on "Rollback".

...

This manipulation allows you to go back to a previous step and cancel the unwanted merges.

...

The datasets concerned by the cancelled merged offers will return to the "Ready" status after this manipulation.
