How do you implement product line with DNG Change sets' dependency?
Hi,
In DNG, you have change set dependency: a given change set is dependant of other CS when it modifies the same artifact as the others.
In product line, you might want to transfer features (i.e change sets) from one stream to another (i.e variant) without taking all dependant change sets (which could be unwanted features).
How do you implement product line in DNG with change sets dependency?
Thanks!

FORUM ADMINISTRATOR / FORUM MODERATOR / JAZZ DEVELOPER In 7.0.1, in DNG, you will have the ability to deliver a change set without being required to also deliver its dependencies. Before 7.0.1, you would have to either deliver all of the dependencies, and then manually "edit out" the changes you don't want, or you would have to manually "recreate" the changes you want in each variant. Of course, those manual steps can be expensive and error-prone, so you probably want to upgrade to 7.0.1 before doing this operation extensively.

FORUM ADMINISTRATOR / FORUM MODERATOR / JAZZ DEVELOPER Hi Hugo
There is guidance on using configuration management here https://jazz.net/library/article/90581 - this discusses on changeset size, and links to specific articles about what the authors call "multistream" and "multistream concurrent" development strategies.

Hi,
Thank you for the answer.
I have already read https://jazz.net/library/article/90581 and all related articles, which I found really interesting!
However, these article do not adress change set dependecies (change set size doesn't solve the problem too).
For instance you take this article:
It states that:
"The changes for any variant might be:
But this is not applicable for change sets in DNG as changes can be dependent to one another (i.e changes are not shareable if I have to share unrelated changes too)
I am really curious to understand how to implement Product Line with DNG,
Thanks,
Apologies I pasted the wrong link - I meant to point you at this article, which does discusses changesets https://jazz.net/wiki/bin/view/Deployment/CLMCfgMRecommendedPractices
Our services team is in the best position to advise you in detail about managing your configurations - you could talk to your IBM or partner sales team about this.
