Description

DNG ReqIF Import shall move imported artefact to correct hierarchy position (according to ReqIF SPEC-HIERARCHY), even if that artefact has a parent in DNG before import, and that parent is not part of the imported ReqIF

DOORS Next ReqIF Import currently has the following behavior:
If an artefact B has a parent artefact A before import, and that parent artefact A is not part of the ReqIF being imported, then DOORS Next ReqIF Import will not move the (child) artefact B during import, even if the ReqIF contains a different SPEC-HIERARCHY position for the artefact B.

DNG ReqIF Import provides no information (e.g. error, warning) that the artefact has not been moved to the position indicated in the ReqIF via SPEC-HIERARCHY.

An abstract example:

DNG before import:
A
>B
C

I.e. A is the parent of B; C is the sibling of A.

ReqIF to be imported:
C
>B

I.e. C is now the parent of B; A is not part of the ReqIF.

DNG after import:
A
>B
C

I.e. B was not moved to its new hierarchy position as child of C, even though this is part of the ReqIF's SPEC-HIERARCHY information.

Expected behavior / DNG after import according to this Idea:
A
C
>B

I.e. B has been moved to its new hierarchy position as child of C (according to SPEC-HIERARCHY in ReqIF).
Note: A not removed / deleted, since remove / delete is currently not a feature of DNG ReqIF Import.

The DNG ReqIF Import shall move imported artefacts to the correct hierarchy position (according to ReqIF SPEC-HIERARCHY), even if that artefact has a parent in DNG before import, and that parent is not part of the imported ReqIF.

This idea is derived from IBM PMR TS008422351 (https://www.ibm.com/mysupport/s/case/5003p00002eCLfpAAG/). In this PMR, IBM stated that the current behavior of DNG ReqIF Import is working as intended / as designed.

Motivation / Reason

The current behavior of DNG ReqIF Import means that after a DNG ReqIF import, any artefact that has a parent may be in the "wrong" hierarchy position (i.e. not in the hierarchy position indicated in the imported ReqIF).

The user is not made aware of this via DNG ReqIF Import or in any other way (e.g. error / warning).

Even if the user is aware that an artefact is in the "wrong" hierarchy position, the user has no information about what the correct hierarchy position is.
