**As** a project member
**I want to** assign to and see the assignment of a work package to a stage/gate
**so that** I can better understand the context the work package is in.

Assumes ###58159 is done.

**Acceptance criteria**

* Work pages receive a new attribute: The gate/stage they belong in.

* \[open\] What is the name of the attribute?

* \[open\] Can a work package be assigned to multiple stages? Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * \[open\] Begin of the insertionIf so, are there any limitations, e.g. that a work package can only be assigned to consecutive stages?

* \[open\] If the work package dates are limited by the associated stage/gate, are they then limited to the interval created by the min of the associated stages and the max of the associated stage?

* \[open\]End of the insertion Can a work package be assigned to a gate (checklist items)?

* The attribute can be administrated same as every other attribute (e.g. status, assignee, version).

* It can be moved in and out of an attribute group.

* \[open\] Should this be an attribute that is seeded? If so, which group should it be seeded into?

* \[open\] Should existing installations get the attribute activated for their existing types? Assumption - no.

* The attribute's value is displayed including the colored type indicator prefix in both the split/full view as well as the table.

* The attribute can be changed via an ng-select.

* Begin of the insertion\[Technical detail\]End of the insertion Begin of the deletion \[open\]End of the deletion Getting the data for displaying the prefix should be simpler here, but it will require coding a variation of the autocompleter.

* The attribute can be added as a column to the work package list.

* The table can be ordered and grouped by that column. The order is not by name of the gate/stage but by the order the gate/stages are in.

* \[open\] In case a work package can be assigned to multiple stages/gates.

* What is the correct order? Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Begin of the insertion\[Assumption\] Stages and gates already have an order so work packages assigned to a stage/gate should use that order.

* The attribute can be used as a filter.

* \[open\] What are the operators available? Assumption: 'is (or)', 'is not', 'is empty' and 'is not empty'.

* Begin of the insertion\[open\] WhatEnd of the insertion Begin of the deletion \[open\] WhatEnd of the deletion are the values available? The stages/gates active in the current project or those in the current project and its descendants? The current behaviour with all of the other fields is to only shows those of the current project. If the filter is used in the global list, all stages/gates should be shown.

* \[open\] Should there be stages/gate specific filters to be able to have filters like: 'Work packages which's gate is in 5 days'? Assumption - no.

* The attribute is journalized.

* \[open\] Which messages are Begin of the insertionprinted in the activity?End of the insertion Begin of the deletion printed.End of the deletion

* In case the associated gate/stage is later disabled in the project administration, the value is no longer displayed, changes are not shown in the journal and the work package are not found via filters (see ###58163).

* The API v3 has a dedicated resource for Stages/Gates.

* GET endpoint for referencing selected stages/gates.

* GET endpoint for selecting all available (active) stages/gates of the project when selecting the value of the attribute.
