In RDNG, can I embed a module within another module?

Will Cummings (37●8) | asked Mar 28 '17, 5:57 p.m.

I have gone through great pains to create modules containing requirements artifacts.  Now, I'm trying to create a new parent module that will have embedded within it the other modules, but when I try to "insert existing artifact", the artifact (module) I want is not available in the list box, nor can it be found even when I search for the exact ID.


What could I be doing wrong?  If a Module is an artifact of artifacts, seems one should be able to continue to nest...

Thanks

Hello Will,

You cannot add a module within a module.  I found an old enhancement request for this feature which was reviewed and they did not include the feature. 

Enhancement 55903: Provide RRC "module within a module" support

You can submit a new request if you'd like this feature reconsidered.

I hope this helps.

Thank you Erica.  After reading the enhancement request's proposal and reasoning, I am puzzled why the development board decided to kill it.  Seemed perfectly reasonable to me (I know - statements like that drive developers nuts... I am one...).


What's the process for re-requesting it?  I'm very new to the forum and to Rational in general.

A module is not exactly an "artifact", even though it has such artifact type associated. Put it simply, a module is a "requirement collection", while a requirement artifact is just a "requirement".

If nested module/collection is allowed, the first issue (in a pure technical perspective) pops up is cyclic referencing. For example, Module A contains Module B, Module B contains Module C, and Module C contains Module A. This is my own opinion, and may not be the reason that development rejected the enhancement request.

As the enhancement request is very old, you can submit a new one in the RFE community.

Thank you Donald.  Hadn't thought of the circular reference problem (doh!).  Be that as it may, still would be nice to have a collection of collections...  Hmm...  there is something called a "Collection" as well in Rational; I'll have to look into that.


Thanks for the link to the enhancement request page.
