While processing  replacement Orders [Using Call Centre functionality] with card payments, It looks as if we have process full payment against Replacement Order, which would be similar to processing a completely unrelated New Sales order;

Expectation was that the Return Order Value nets off with the Replacement Order Value and no additional payment is required to complete the order, in case of like for like Replacement;

Is this standard AX Behaviour or a glitch in Call centre functionality;

Any guidance would be much appreciated;
