Process message window is not invoked if Process Order API is used to update line details.

Hi,

When we are booking Sales order for a particular customer, credit check hold is applied and the message ' Credit check hold has been applied. Overall credit limit exceeded at site level’ appears in process message window.

However, when we use process order API to update tax details for the order line before the order gets booked, credit check hold gets applied but message does not appear in process message window. I read from Oracle support that if initialization is done before using the API, process message window gets invoked.

I have done the following initialization before calling the API but it does not seem to work.
