Good day! I am currently experiencing some problems displaying custom error messages from BADI LSO_CHECK_BOOKING. I have implemented this Badi and is appending error messages in CT_MESSAGE_TAB however when the message is displayed in portal, the custom message is not displayed. Instead, SAP displays a predefined error "Error When Creating Prebooking with the data entered..."
Is there a way for me to display my custom error message instead of the predefined SAP message?
Thanks a lot.
