Thanks Sunil/Tushar,
But as a sell side vendor we have multiple buy side connections and luckily this buy side accepts the fills post cancel ER. But if another buy side client do not accept fills post cancel, then how would that need to be handled in FIX?
We have also encountered that most of the buy side do not support unsolicited messages.
From a multiple connectivity perspective what could be the best solution and acceptable to all?

Sachin
