Hi @gisgis​ 

I suggest you to use the transformer Cloner.

In the number of copies, you can select the attribute that you have.

After, you can use the transformer aggregator.

Thanks in Advance,

Result:

Workspace attached.

thanks a lot but there is one small thing, what if I have some more lines with the same value which of course I dont want to group ? I need the same number of output lines as input. I updated my table

Thanks @gisgis​ for your reply.

I inserted the transformer counter before to create a ID for each line.

Attached the Workspace.

Thanks in Advance,

Danilo
