One cannot place a target and stoploss at the same time for their CNC position. You can either place a target or a stoploss. This is because if you were allowed to place a target as well as a stoploss for the same CNC position and your target was executed, then your CNC position is already sold out. But the CNC stoploss order will remain open in the orderbook and if it gets executed too, then this will become a new CNC sell trade without actually having the holding in your account. It will lead to short delivery and an auction penalty.
If you intend to trade this position for intraday only, then you could keep a stoploss only and then if your target is achieved, cancel your stoploss and exit by placing a target.
