you could use Loop Attributes and inside that Generate Attributes with something like: match = match || contains(%{attr}, "|")
Initialize match with false, and filter records that have match = true after. The expression changes to true if one of the attribute values contains the character |.
If it were a different character, you could use Generate Aggregation with the concatenate function - but unfortunately it uses exactly | for separating the resulting string.
