How to aggregate data from the multiple fields into one new field?

[CBabb]

Hi - I have a field (let's call it Field X) in each Deal and I have multiple Deals related to one Contact.

I want to aggregate the data from the Field Xs and concatenate them into Field Y.

Is this possible?

Hi @CBabb,

Yould you specify what exactly the aggregation / concatenation should look like? If you have deals with values "A", "B", and "C", do you want to field on the contact record to say "ABC"?

Best regards
