I am using the aggregator transformer to take multi part polygons across NI, grouped by Local Government District, so when the data is displayed and selected on a map the records in one district will be selected as a multi part. I want to keep all unique identifiers and addresses for the records, as well as other attributes. I have currently got all the attributes to remain by using the assemble hierarchy section in the transformer using LGD as parent id and unique id as the id, but the group by doesn't seem to be working as the records are being selected as individuals polygons, not multiparts.
Question
Is there a way to group by an attribute in the aggregate transformer so that they are multipart but keep all the other attribute information?

Hi @nicole.mcstay thanks for your question! Do you have a sample of your data that you could share? What version and build number of FME are you using? This seems like this might be a bug or an enhancement request but we would need to have a reproduction to investigate and share with the developers.
Happy to help, Evie

We can’t send the data as it’s under copyright. I am using FME(R) 2022.1.1.0 (20220728 - Build 22623 - WIN64).
This is my workspace.
Before the data goes through the aggregator it has the LGD and Fusion ID assigned (see below)
After it has ran through the aggregator the records still contain the data 9see below) but they are not multipart. Each record is still highlighting as an individual rather than all records within the LGD highlighting together.
