Hey everyone,
I’m getting a warning prompt while trying to duplicate a family type in Revit.
I am not proficient yet with transactions within Dynamo environment.
So I would like to know what I’m doing wrong and how can I remedy this?
Thanks in advance,
Yash
I am using Revit 2022.1 with Dynamo 2.12.
I hadn’t noticed that there were already few older topics related to transaction management in this forum. So I thoroughly went through those to figure out the solution to my topic.
Just had to take care of the placement of transaction nodes and their inputs.
Kudos to the community! 
When creating a new piece of code, I’d recommend starting with having it split up in quite a lot of code blocks, all covering just a few or even just a single step of the process.
After you get that functional, you can always “summarise” all that in a single code block after. As you can see the result of each individual line of code then, it becomes a lot easier to figure out where the source of a problem would be.
Hi @PauLtus, thanks for replying!
Yeah I usually start with placing individual nodes to the graph and then once they seem to function properly I convert them to code blocks for better legibility.
Although in this case I thought it would be better to use textural scripting for the second part of the graph for desired execution flow. But again, this was before I understood how transaction nodes work.
Alas, lesson learnt! 
It seems you already got the right workflow then. 
Even if I’m pretty confident I can do it one go I tend not to, when something goes wrong and everything is already tightly coded it can take quite some time dissecting to find out what exactly went wrong.
