You can enter a list of records parameter, AFAIK it won’t break simply it won’t work. The field expects an expression that resolves to a single record.
Also, better use the DataStructure_DataType + RecordLink field combination instead - it is better optimized for SQL the least. -
(The above example uses the first iteration of this “project”, the RecordLinkExpression field) As per Reinier’s remark, this statement is incorrect, I was mislead by the wrapper process component.
The component in fact uses the DataStructure_DataType + RecordLink field combination.
