Hello,
I didn't find a way byself to solve my problem. So, now I will ask the community.
The problem:
I have two forms. Both forms have one field with the same configuration, like a grouping field - "ID":
form1 - metadata
form2 - requirements
For each entry in the form "metadata", there can be multiple entries in the form "requirements".
Now i would like to merge the two forms by the field "ID".
The result should be look like:

I had try many ways with the "TableView Merger" but I didn't find the right way.
Can you help me?
thank you.
