I think this needs to be clarified to avoid confusion. The column "Req'd" in the spec is not the only way for FIX to declare a field to be required or not. The comment column is another possible source. The position of a field in a repeating group is a third possible source when using the tag=value syntax. The previous poster actually quoted from the comment in the spec. What happens if you do not send tag 11 in the Execution Report responding to a New Order Single? The submitter of the order will have a hard time to know which report refers to which order entry message if he does not wait for a response before sending another new order. From then on he could use the exchange order ID (tag 37) but it is neither permitted nor recommended to omit tag 11 in the Execution Report in the plain vanilla cases. There are very few exceptions where tag 11 is not available and thus cannot be returned. What advantage does it have to suppress tag 11 on an ExecutionReport? I would like to understand why that makes life easier for the recipient of order messages, regardless of what the spec says.
