Hi
I'm trying to group data, and assign each group an id. And each like within that group a line id.
I have Carrier_name, direction and delivery_country_code and scan_date as criteria for main group.

I assign each of these an ID

Then each parcel number should have a ref to the LM_Scan_group
And have a forth running number within that group.

Desired result

I have attached sample workflow with sample data.
Thanks in advance,
