Hi Hurra,
BDDs and IBDs have their root in UML. BDD ~ Class Diagram and IBD ~ Composit Structure Diagrams.

The BDD you can somehow regard as a structured bill of material, it focuses on what a thing consist of.

IBD focuses on how the different things within a thing interact with each other.

Let’s say you have a block representing a special kind of wheel. This wheel will be part of a car type A typically with multiplicity 4. Further on this wheel could be part of many other car types.

If you want to express how wheels interact e.g. with the power train, you need to differentiate the four wheels somehow like left-font, right-rear,…, and these are the “instances” or more correct in SysML "the right-front wheel is a property of car type A with the role to be the right front wheel of type "Wheel".

If you would only use BDD you would need to duplicate the "Wheel Types" (Blocks) as many times as wheels you have. The wheel block could even be a complex thing (wheel rim, tire, valve,…), you would need to double as well. In other words BDD and IBD is all about OO in SysML.

Just wondering why you need that EA log stuff at all, because as I remember you are using PTC Integrity for versioning.

If you have version controlled packages, the users must lock the package against the version control system, and the information who changed what when you should get from you VCN in use.

Ok I got it!
Thank you KP!

It is amazing to see, how capable you are, in beaming back your users in newbe stage with each new major version. ;)

In a fist step I would run a Project Integrety check.

IBD seem not to have this problem (only BDD).

On my next try to bring V14 in production, I got the following problem.
When I have a block diagram created with V13 showing the ports on the bock borders, and I move the block a bit to another place, ports on the left and right border are displaced.
Ports on the left are outside of the bock and ports on the right are inside of the block.

Yes, Tagged Values are intended to extend too what is not there, but this stuff is already there at least for use cases. So, no need to use tagged values.

When looking to buid 1423 to see if the bock/port issues are gone, I realized that in V14 it is only possible to set the port type on a bock border rendered port.
This is quiet indirect and in pre V14 it was possible to do that without putting the port to a diagram.

So, please provide the Advance/Set Property Type… on project browser again and in addition in the Parts/Properties/Interaction Points.

I have not jet verified. However according Sparx this is fixed with Pro Cloud Server Version 2.1.21.
So quick! :) :) :)

Elements you can drag and drop.
But relationships/connectors you select in the toolbox.
After that click on your source element (hold left mouse button) and move to your target element (release left mouse button).

Yes, may or may not  :-\

EA/UML does not really have an “any Purpose” table.

However you have several options.

-Put you scenarios as natural language under Properties/Rules/Scenarios/Description
-Put you scenarios as sequential steps under Properties/Rules/Scenarios/Structured Specification
-Create e.g. sequence- or activity-diagrams representing the scenarios and associate those e.g. by <<refine>> association to the use case.

What do you put in your tables?
The use case scenarios, right?

I tried an older worker version and this seem to work.
I will insert a official bug report.

It seem to me to be just another QM issue.
