For example - "new Sales Invoice" - the successful response is a kitchen sink of mostly irrelevant information (such as Customer information - which of course we would already have).
I know the response for a POST or PUT is the same as for GET - very nice and simple.
But total bloat.
Please add ability for POST/PUT to request a concise response - all that's really needed is the ID of the new SI.
And if we need more info, we all know how to GET it.
