A question:
When did we change this?
A request:
(Please,) Let me know when we changed this.
A request, combined with a question:
Please, let me know the following: when did we change this?
So, for correct word order it is important to choose a form (a question, a usual sentence or something more complicated).
To my BrE ears the first two sentences have slightly different meanings. The first question:"When did we change this?" conveys an aggressive tone, as if the boss is asking his subordinates why something he always thought was X is now not-X. It is obviously less aggressive than "when did you change this?" but it is aggressive, nonetheless.
The second question is more nearly neutral, but if I were a subordinate and the question was asked by my boss, I should be a little nervous.
The third is just a longer way of asking the second question.
